Sex, Romance & Nudity

Other than a few kisses and some romantic tension, there's only one sex scene, but it's extended, explicit, and meant to arouse. Oral and genital sex, manual stimulation, genital penetration, sucking nipples and genitals, and orgasm are described in detail with some crude words like "clit" and "c--k." Good examples of consent are modeled, and birth control and being "clean" are talked about. A few times adults talk about sex or sex acts like sixty-nining, butt stuff, and getting a "hand job."

Positive Role Models

Olive and Ahn are good models of women in STEM. They're extremely loyal and supportive of each other, and Anh creates chances to support other women, especially BIPOC women in STEM. Adam is very protective and kind on a personal level toward Olive, but to his students he's harsh and uncompromising and seems uncaring. Olive makes a grand gesture out of compassion for Anh and models perseverance in advancing her research and career.

Diverse Representations

Olive reads as White, is from Canada, and is very slim. Adam implies he's Jewish and is very tall and powerfully built. Best friend Anh's family is from Vietnam, and she identifies as a woman of color. Roommate Malcolm reads as White, dates men, and enters a romantic relationship with another man. Olive wonders if she's asexual.

Educational Value

An author's note explains Title IX and offers websites supporting women and BIPOC women in STEM academic fields. The overall story provides insight into graduate and postgraduate academic life and careers, especially in STEM fields.

Positive Messages

You have to be strong and tough to make it in the academic world, especially in STEM fields. Don't be afraid to speak up when you've been harmed or you learn about something unethical. Your web of lies will eventually come to light, and when it does, it may cause more hurt than being truthful from the start would have.

Strong language includes "c--k," "d--k," "f--k," "pr--k," "s--t," and more. Adults mention past excessive drinking, look forward to free alcohol at university events, and have a weekly "beer and s'mores night." Two characters remember one of them projectile vomiting after eating bad shrimp, but it's not described. Olive is an orphan with no family. Her mother died of pancreatic cancer, so grief and loss are important themes, along with the struggles women still face in STEM-related fields.

What's the story.

THE LOVE HYPOTHESIS is about Stanford graduate student Olive, who needs to convince her best friend, Anh, that it's OK for Anh to date a guy Olive had recently been seeing but wasn't really interested in. So she hatches a plan to "fake-date" none other than the Biology department's most prestigious professor, Adam Carlsen, who's also a huge jerk. As Olive and Adam's ruse gets harder and harder to keep up, Olive starts to feel like she wishes their dating wasn't actually fake. Will she be able to untangle her web of lies without ruining everything, for everyone?

Is It Any Good?

This romance set in the lofty world of a prestigious graduate school program has its ups and downs. It's refreshing to see women in STEM represented and important to highlight how much many women struggle in that world. The Love Hypothesis has some funny banter, especially with colorful supporting characters. Readers who enjoy very familiar romcom tropes will feel at home here, because this story is chock-full of them. The one explicit sex scene is easy to skip for those who aren't interested. A big drawback is Olive's truly bad and unrealistic decision making, which strains believability and takes the reader outside the story.

Talk to Your Kids About ...

Families can talk about the graphic sex in The Love Hypothesis . Is it over-the-top? Realistic? Is reading about it different from seeing it in movies, videos, and other media?

What are some concerns about reading or watching explicit sex ? Do you compare yourself or your body to the characters? Does it make you afraid, feel creepy, or unsure about what sex is like for real people?

What about all the strong language? Is it realistic? Is it a big deal? Why, or why not?

Talk about women studying and working in STEM fields. What are some of the challenges Olive and Ahn face? How do they deal with them? Who supports them? What can men do to make STEM fields more welcoming and inclusive?

The Love Hypothesis by Ali Hazelwood | Book Review

Posted August 12, 2021 by Jana in Adult Fiction , Book Review / 4 Comments

When a fake relationship between scientists meets the irresistible force of attraction, it throws one woman's carefully calculated theories on love into chaos. As a third-year Ph.D. candidate, Olive Smith doesn't believe in lasting romantic relationships--but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees. That man is none other than Adam Carlsen, a young hotshot professor--and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding...six-pack abs. Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

So. I’m really not the best at reviewing books I absolutely loved because I don’t have many words! We all know I love fake dating romances, and I loved the idea of a STEM romance because science is cool and I really love and miss Big Bang Theory (and no, this isn’t like that per se, it’s just got super smart people spouting off science facts). Anyway, I immediately gravitated toward The Love Hypothesis because it sounded fresh and funny and unique. It was all those things and more! As always, my main points are bolded.

1. This book is so, so nerdy and I loved it. The people are a little awkward and extremely smart. There’s strong women in science, and I loved learning a little bit about the challenges women face in this field. Every chapter starts off with one of Olive’s hilarious little scientific hypotheses about love and life, each one teasing a bit about what’s coming up in that chapter. These made it very hard to stop reading because I’d get to the end of the chapter and decide to read and then BOOM. I’m intrigued again and must continue reading. Very clever. A lot of the book takes place on campus in the labs, and I thought it was such a fun setting with people working late and running experiments because science doesn’t wait for people to sleep or eat. There’s lots of science talk, there’s a science convention and people get all excited about presenting posters and attending talks and it’s all just so much fun. It reminded me a bit of Ross’s paleontology convention from Friends, just no Barbados.

2. Olive is sweet and strong. She’s smart and strong and totally dedicated to her cancer research. She’s looking for a lab that will accept her the following year so she can continue her testing with better equipment and proper funding. It matters more to her than pretty much anything. Everyone she’s ever loved has died, so she’s very reluctant to get too close to anyone except her two best friends. Relationships are scary and also a little confusing for her. It takes her a while to sort through her feelings and figure things out, and I loved watching her grow and evolve.

3. Dr. Carlsen (Adam) is a dreamboat. He’s seen as rude and lacking in compassion. He’s hard on his grad students, but it’s because he wants them to succeed. He’s super sexy and thoughtful and protective of those he cares about. He’s sarcastic, flirty, suave, and all the things I love in a hero. Olive is a little inexperienced in the love department, and there’s a scene where he puts all of his focus on taking care of her. Consent and comfort are so important to him, and the entire scene was him making sure she was ok. It just melted me, and I’ve never read another scene quite like this one.

4. The chemistry between Olive and Adam is insane. These two can throw the banter back and forth forever and get me laughing, but they can also build up a level of tension that makes you squirmy. There’s an age gap of about 8-9 years between these two, so Olive loves to make fun of him for being old. She also loves to make fun of his healthy eating habits. He likes to tease her about her love of sugar and poor taste in food. But then there’s a scene where Olive’s best friend kind of forces her to kiss Adam after he’s just pushed a car out of the road and is all sweaty, and wow. And then there’s a scene at the department picnic where Olive has no choice but to coat his muscley back in sunscreen (poor girl), and wow. Their relationship is sweet and spicy and tender, and I just love them.

5. Olive’s best friends, Anh and Malcolm, made me so happy. They are both scientists and work together, although their research is all different. Anh is the loyal best friend, who also mothers Olive and makes sure she doesn’t get skin cancer. Malcolm is Olive’s roommate, and he’s pretty much made of rainbows and sunshine. They love to discuss hot men and other fun things. I would love to be a part of this friend group. Adam’s friend, Holden, is another favorite character of mine. He gives great advice, really cares about his people, and is so happy all the time.

6. There’s some deeper issues at play that run throughout the story, including the #MeToo movement. All were treated with sensitivity and respect. 

7. There’s so, so much humor! I actually laughed out loud at one point, which never happens to me. I’ve been known to smile or silently laugh, but this was an actual audible laugh that startled me.

8. The writing is also spot on, and flowed so nicely that the pages practically turned on their own. 

All in all, this is a stunning debut for Ali Hazelwood. Strong women in science, a sexy doctor hero who values and supports those women, hilarious banter, strong friendships, and a very sweet love story all wrapped up into a glittery, sugary package. What’s not to love? I highly recommend The Love Hypothesis, and cannot wait to see what Ali Hazelwood does next!

The Love Hypothesis – Book Review

• April 10, 2024

If you are a reader of romantic comedy, we’ve got you an extraordinary book for your next read. Join us today as we review “The Love Hypothesis” book, covering its storyline, characters, and where to get a copy. At the end of this book review, trust me you will have made up your mind to pick up this novel from the shelves.

What Genre is “The Love Hypothesis” book?

This book is a contemporary romance novel by Ali Hazelwood, published on September 14, 2021 by Berkley Books.. It falls under the broader umbrella of romance fiction, which typically focuses on romantic relationships and emotional development between characters. Within the romance genre, “The Love Hypothesis” might also be categorized as a romantic comedy or romantic drama, depending on its tone and themes.

A Glance into “The Love Hypothesis” Novel

“The Love Hypothesis” is an absolute page-turner that follows the story of a biology Ph.D. student, Olive Smith, and a professor at Stanford University, Dr. Adam Carlsen.

Fast forward nearly three years, and we catch Olive in a desperate act: she’s faking a kiss with a stranger, hoping her best friend would mistake it for a real relationship. In a bid to convince her friend, she locks lips with the first person she sees, only to realize it’s Adam Carlsen, her school professor—a total jerk.

Unexpectedly, Olive, usually quite perceptive, didn’t anticipate kissing not just any stranger, but a professor. What surprises her even more is when Adam Carlsen agrees to pretend to date her, but it becomes apparent he also has ulterior motives, realizing a genuine relationship could serve his own ends within the university community.

As Olive and Adam’s interactions fuel more speculation and gossip about their relationship, they find themselves slipping into a fake dating scenario, each with their own reasons for doing so. As the facade of their fake relationship begins to blur the lines of reality, Olive and Adam find themselves grappling with unexpected emotions. The gradual realization dawns on them both that what started as a charade has evolved into something genuine. The question looms: how long will it take for them to acknowledge their true feelings and abandon the pretense they’ve been upholding?

Did we love the overall storyline

From the very first chapter, I was hooked. The pull was undeniable, filled with glamour, sensuality, and an intoxicating charm! As a huge fan of the fake dating storyline, I found this book incredibly enjoyable. It offers not only lighthearted fun but also a depth of emotional vibrancy.

Featuring a brooding male lead, a quirky female protagonist, and a narrative blending science with contemporary romance. The story unfolded through witty banter over drinks, heated arguments via text and casual conversations in the lab break room. Through these encounters, Olive finds herself growing closer to Adam than she ever thought possible. The storyline is captivating, blending elements of romance and humor smoothly, making it impossible to put the book down.

Editor’s Remark

As an avid fan of romantic comedies, I found myself utterly captivated by this book. While immersed in its pages, I experienced a whirlwind of emotions, from hearty laughter to the occasional tear shed, as the characters’ personalities resonated deeply with me. Have you ever read a novel and wished it would never end? That was exactly how I felt about “The Love Hypothesis.” I found myself completely engrossed, wishing the story could continue indefinitely.

In general, “The Love Hypothesis” delivers a delightful reading experience that will leave you smiling and feeling butterflies in your stomach. Hazelwood’s writing possesses a sharp humor, showcasing her talent in creating unforgettable jokes. The book is just so entertaining that I highly recommend it to anyone looking for a charming romantic escape! You can get yourself a copy of this amazing book from Amazon .

Frequently Asked Questions

The story centers on Olive, a graduate biology student, who finds herself entangled in a fabricated romance with her professor, Dr. Adam, while attempting to persuade her friend Anh about her dating experiences.

This book is ideal for those seeking a swift and effortless read without any lingering uncertainties.

In “The Love Hypothesis,” Olive’s age is 26.

Review: ‘The Love Hypothesis’ by Ali Hazelwood

The Love Hypothesis

As a third-year Ph.D. candidate, Olive Smith doesn't believe in lasting romantic relationships--but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees. That man is none other than Adam Carlsen, a young hotshot professor--and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding... six-pack abs. Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

I received a copy of The Love Hypothesis from the publisher when it was released, and the book had been staring at me to read it whenever I walked by it. I was hesitant because I’ve been burned lately by cartoonish covers being labeled as Romance, but once I started reading them, I realized they should have been labeled Women’s Fiction/Chick Lit. In the case of The Love Hypothesis, I didn’t get burned this time because this book was a Romance, and I enjoyed the storyline with this one and adored the characters.

This was the first book I read from author Ali Hazelwood, too, and I’m kicking myself for not reading her sooner. The whole time I was reading this book, I couldn’t wait to tell my oldest daughter, who is away at college right now, about it. This book is something I know she would enjoy, especially with it being a STEM romance.

I’ve always enjoyed the fake dating storyline in romance books and loved how Olive and Adam ended up stumbling into it. The whole reason behind the ‘fake relationship’ was to convince Olive’s friend she had moved on from a guy that her friend now was seeing that Olive used to date. Adam agreed to fake date Olive until a certain deadline. The more time they spent together, though, the more one of them or both were going to start having genuine feelings, and I was all for them developing into a real relationship, especially with how they had an instant chemistry between the two.

I adored Olive’s character and hated knowing what she went through when she was younger. She was a driven, brilliant character that I connected with right away, and she reminded me of my oldest daughter. I hated what happened to Olive during the conference and wanted to comfort her and encourage her to tell someone. Yes, this scene did bring out some emotions in me because I had experienced something similar while working in the Navy and hated that I never had the encouragement to do something about it. No woman should ever feel they can’t speak up about this issue, especially when the person threatens her. I’m grateful for how the book addressed the issue and thankful for Olive having some amazing friends and how Adam handled it, too.

Adam may have been a difficult college professor and a grump at times, especially to certain people, but he wasn’t that way with Olive. He had agreed to fake date her, and he was one of her biggest supporters. I loved how he was with her when they did eventually give in to their attraction to one another. (I highly recommend listening to the book because you’ll get a chapter in his POV, and you’ll fall head over heels for the man.)

This book is told mainly in the FMC’s POV, which I usually prefer reading dual, but I didn’t mind with this book. I preferred not knowing what Adam was thinking because it made it more mysterious.

Overall, I really enjoyed this book, and I give the story 4.5 stars; I can’t wait for my daughter to read it when she has time between taking notes, writing essays, and studying for her degree. I also can’t wait to read more books from Ali Hazelwood.

Here are some of the trope(s)/element(s) that I found while reading this book that may appeal to readers: 💙STEM Romance 💙Fake Dating/Relationship 💙Age Gap 💙Grumpy vs. Sunshine 💙Slow Burn

About Ali Hazelwood

I’m originally from Italy, lived in Japan and Germany, and eventually moved to the US to pursue a Ph.D. in Neuroscience. I recently became a professor, which absolutely terrifies me. When I’m not at work you can find me binge-watching shows with my three feline overlords (and my slightly less feline husband), running, or eating candy.

Review: The Love Hypothesis, by Ali Hazelwood

[fa icon="calendar"] Sep 13, 2021 11:08:00 AM / by Suzanne

The Love Hypothesis pairs a 26 year-old grad student/researcher with a 34 year-old faculty member/researcher in a fake dating relationship for the ages. I flipping loved this book. Everyone told me I'd like it, but I couldn't stop picturing the male love interest, Adam Carlsen, as Adam Driver (this book started as Reylo fic) and I knew, just knew  I wouldn't like it because of that. I was so wrong.

This is somehow a debut novel. It doesn't read like a debut novel. It reads like a romance author at the top of their game and gave me all the feelings I want from a romance. I laughed, I cried, but most of all I was swept up in the love story. I read so much romance that it's rare I really feel  the romance anymore, but this single POV story had me convinced that love is real and these two people are in it.

I read this mostly on audio, but when the BOTM copy I had ordered at 2 am showed up a week before publication, I finished the book in print just so I could race through those last 80 pages. And now I'm bereft, having not only no more pages to read but no more books from Ali Hazelwood either. This book is nerdy and queer and funny and fresh and *ugh* I loved it.

Adam is determined to have Olive's consent at every step of the way, and Hazelwood manages to make it hot as hell. It's a slow burn which makes sense for the plot and characters, but it's definitely a burn. Turns out, this author can write great sex, too! Miracle of miracles, we get character development, plot that makes sense, quality sexytimes and a whole range of feels from a single book. 

One note - Olive is pretty clearly demisexual, but I don't think the word ever appears on page and it's clear she's struggled with her lack of sexual attraction in the past. On page, she says things like "I realized I could only be attracted to people if I had an emotional bond and trust with them, and even then not often" or "I wondered why I didn't seem to experience attraction, especially sexual attraction, like normal people". So this language may be off-putting to ace-spec readers, but it also feels natural for the character given her general dense-ness when it comes to caring about herself and not just science.

So, like any self-respecting biologist, Olive panics and kisses the first man she sees. That man is none other than Adam Carlsen, a young hotshot professor—and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding...six-pack abs. Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

Book Review: The Love Hypothesis

The Love Hypothesis is a cute romance novel that takes place in an academic setting. Olive, our protagonist, is a PhD STEM student attending Stanford, and Adam, her love interest is a professor at the college. I was initially a little hesitant about this book because while the age gap between Olive and Adam isn't concerning, their power dynamic is. Conveniently, however, it is revealed that Adam is not one of Olive's professors and manages another section of students. Even though Adam and Olive were never really "teacher-student," it still made me a little uneasy, especially since the two attend the same college. The novel basically establishes its plot through Olive and Adam having a fake relationship together. Adam needs this fake relationship to convince his higher-ups that he's not leaving Stanford and has put down roots, in order to unfreeze funds needed for his research projects. Olive, on the other hand, needs a fake relationship to convince her best friend Ahn, that she has no feelings for a boy she had gone out on a couple of dates with, after realizing Ahn is interested in the same boy herself. In order to persuade Ahn to pursue her feelings, Olive strikes up this fake-dating deal with Professor Adam Carlsen, thus leading the two of them into a real future together.

The Love Hypothesis, in my opinion, has everything critical for a good, cheesy, romance. The fake-dating trope, many sweet situations, and a love interest who seems cold and cruel on the outside, but turns out to be a softie just for Olive. While the novel may have the right ingredients for a swoon-worthy romance, however, there was something missing. Olive as a protagonist was a very 2d character and was someone I could not find myself relating to or even being interested in. While it was refreshing to see a female woman lead pursuing a career in STEM, there was nothing else all that interesting about Olive. I also didn't like the author's choice of using the topic of sexual assault only as a plot device, in order to bring the story forward and the characters closer.

On the other hand, Adam was a classically written love interest. Strong on the outside, and soft on the inside, he had all the criteria needed for a typical male lead in a romance novel, and while it may seem overdone to some, I think Adam was a great portrayal of such traits.

Overall, The Love Hypothesis was an interesting romance novel, and I enjoyed its academic setting and some of the scenes involved. However, there were a couple of aspects of the story that could have been tweaked to make the story more enjoyable. In my opinion, many romance-lovers would probably enjoy this novel, but I found myself wanting more.

The Love Hypothesis

Quick recap & summary by chapter.

The Full Book Recap and Chapter-by-Chapter Summary for The Love Hypothesis by Ali Hazelwood are below.

Quick(-ish) Recap

Three years prior, Olive Smith talks to a guy when she's in the bathroom fixing her contacts (and can't see) after her Ph.D. candidate interview. She tells him about her passion for her research. She doesn't catch his name but remembers the conversation distinctly and wonders about the guy she met.

In present day, Olive is a biology Ph.D. student researching early detection methods for pancreatic cancer. She kisses a guy randomly in order to trick her best friend into thinking she's dating someone (so that her best friend Anh won't feel bad about dating Olive's ex). That guy turns out to be Dr. Adam Carlson , a young, handsome and highly-respected tenured faculty member in her department. He's also known for being hypercritical and moody.

Meanwhile, Adam's department chair is worried that he's planning on leaving for another university and has frozen some of his research funds. So, Adam he agrees to pretend to be in a relationship with Olive in order to give the impression he's putting down "roots" here, in hopes they will unfreeze the funds.

As Olive and Adam fake-date, they get to know each other. Olive sees that Adam is demanding and blunt towards his students, but not unkind or mean. Olive confides in him about her mother getting pancreatic cancer, which is why she's doing her research.

Olive soon realizes that she has feelings for Adam, but she's afraid to tell him. When he overhears her talking about a crush, she pretends it's about someone else. Olive also hears someone else refer to a woman Adam's been pining after for years and is surprised at how jealous she feels.

In the meantime, Olive needs more lab space and has been talking to Dr. Tom Benton for a spot at his lab at Harvard. When Tom arrives in town, it turns out he's friends with Adam. Adam and Tom are friends from grad school, and they have recently gotten a large grant for some joint research that Adam is excited about. After Olive completes a report on her research for Tom, he offers her a spot in his lab for the next year.

Olive and Adam's relationship continues to progress until they attend a science conference in Boston. Olive's research has been selected for a panel presentation, while Adam is a keynote speaker. There, Olive is sexually harassed by Tom, who makes advances on her. When she rejects him, he accuses her of someone who sleeps around to get ahead. He also says that he'll deny it if she tells anyone and that they won't believe her.

While Olive does finally sleep with Adam at the conference, she soon tearfully breaks things off since she doesn't want to complicate things with Adam's joint research project with Tom. Adam is also in the process of applying for a spot at Harvard.

Olive is certain no one will believe her about Tom until she realizes that the accidentally recorded the conversation where he made advances and threatened her. Meanwhile, Olive's roommate Malcolm has started seeing Dr. Holden Rodriguez, a faculty member who is a childhood friend of Adam's. Olive and Malcolm turn to Holden for advice, who encourages them to tell Adam about the recording. He points out that he thinks the main reason that Adam is considering a move to Harvard is because Olive is supposed to be going there.

Olive finds Adam and shows him the video. He is incensed at Tom and reports it to their faculty. When Adam returns from Boston, he reports that Tom has been fired. Meanwhile, Olive has been reaching out to other cancer researchers for spots at other labs, and she's gotten promising responses. Olive tells Adam that she loves him and that she never liked anyone else. Adam admits that he remembered her from the day he met her in the bathroom and that she's the one he's been interested in for years.

Ten months later at the anniversary of their first kiss, Olive and Adam re-create the kiss to mark their anniversary.

Chapter-by-Chapter Summary

Olive Smith is an applicant for Stanford’s biology Ph.D program. After the interview with Dr. Aysegul Aslan , she ends up in a bathroom nearby unable to see and trying to wash out her eyes because she put in expired contacts.

She meets “The Guy” there, who she assumes is a Ph.D student there. As they strike up a conversation, she tells him that her name is Olive and talks about why she’s applying to the program. She tells him that she wants to do it in order to research a specific topic.

A few weeks later, Olive is accepted into the program.

Years later, Olive is now 26 and a Ph.D. student in Dr. Aslan’s lab. Olive has just kissed a random stranger (in order to trick her best friend, Anh , into thinking she’s on a date) — only to realize that the “stranger” is actually Dr. Adam Carlson , a 34-year-old tenured and highly-respected professor in her program with a reputation for being notorious moody, mean and hypercritical.

After they pull away, Adam accuses her of assaulting him. Olive insists she asked him and he said yes, but he says he merely snorted. Finally, she explains that her friend Anh had hit it off with a guy she’d been dating, Jeremy. Olive broke things off with Jeremy, but Anh felt too bad to go out with Jeremy. To make Anh feel better about it, Olive lied to Anh about dating someone and being on a date tonight. When Anh showed up at the lab, Olive needed to kiss someone so Anh would believe she was on a date.

Finally, Olive apologizes and leaves. She doesn’t notice that Adam had called her by her name (which she hadn’t brought up in this conversation).

A few days later, Olive is still embarrassed by what happened. However, she figures that she’d never crossed paths with Adam before then, so perhaps she wouldn’t cross paths with him again. Meanwhile, Olive is preoccupied with needing to find more lab space for her research on early detection of pancreatic cancer. Today, she also finds out Tom Benton , a well-known cancer researcher and an associate professor at Harvard, is interested in potentially allowing her to carry out her research at his lab at Harvard. He’s going to be in town in two weeks and wants to meet with her.

When Anh sees her, she confronts Olive about kissing Adam Carlson. Olive thinks back to how they met since they were the only two non-cis-white-male students in their class. Beyond that, Anh was her biggest support and best friend.

Today, Anh demands to know why Olive is dating Dr. Carlson. This conversation is interrupted when Adam walks in. He plays along and pretends that he and Olive are together. After they make formal introductions, he tells her to call him Adam, in case her friend Anh is around. Later, when Olive talks to Anh again, Olive continues to pretend she’s dating Adam, and she once again encourages Anh to date Jeremy.

On campus, Olive starts to notice that people are treating her differently and with some level of curiosity. When her roommate, Malcom , demands to know why she didn’t tell him about dating Dr. Carlson, Olive realize that everyone know about her lie. Olive goes to Adam’s lab to tell him what’s going on, and she apologizes to him for it.

Olive notes that he seems very at ease with everyone believing that they’re dating, and she wonders why. Finally, he admits that Stanford considers him to be a “flight risk” (that he wants to leave them for another institution) and that they’ve frozen some of his research funds because of it. Part of the issue is that he’s recently gotten a large grant with one of his collaborator’s at another institution, and the department is worried he’s planning on moving there. He hopes that the dating rumors will make them think he’s more likely to stick around since he’s dating someone here.

A few days later, Olive goes to Adam’s office and tells him she wants to proceed with pretending that they’re dating. Olive notices that she’s been treated much better by everyone since the rumor started. (Apart from Malcom, who dislikes Adam Carlson, and has been shunning her.) Adam explains that he’s looked into it and there’s no issue with it, though he can’t serve in any supervisory capacity for her or serve on her thesis committee or be a part of any decisions if she’s nominated for a fellowship or other awards.

They decide to set some ground rules for their fake-dating arrangement. They decide to be fake-dating while on-campus only, so no personal engagements. Olive stipulates that there’ll be no sex. They also agree not to date others in the interim, since it will make things messy. And they agree that they should get coffee or something regularly to make things believable.

They plan to continue their fake-dating until September 29, roughly a month from now, which is the day after the department’s budget review. Their first coffee “date” is planned for Wednesday at 10 AM.

Later, Olive talks to Malcom, who is still upset with her. Malcom comes from a long line of well-known scientists, and he dislikes that Adam Carlson’s criticism of his research had made his life so difficult. Olive confides in Malcom that they’re merely fake-dating and that she barely knows Adam. She says that he’s just helping her out with the Anh/Jeremy situation (and she doesn’t mention Adam’s reasons for participating).

On Wednesday, Olive and Adam have their first fake-date at the coffee house. They ask each other some basic questions, and Adam pays for her order.

The next week, they meet up again, though Olive is running late since she was getting ready for a meeting she has with Tom Benton later that day. Meanwhile, Adam is a little moody because his department chair has still not agreed to release his research funds. They discuss attending the fall biosciences picnic together so that his department chair can see that they’re together.

They’re interrupted when a friend of Adam’s walks in and greets him warmly. Adam introduces the man to Olive as his friend and collaborator — who turns out to be Tom Benton.

Dr. Benton reveals that he’s heard about Adam’s romantic exploits all the way at Harvard, and he’s surprised to hear the rumors about Adam’s new girlfriend being true. Olive also awkwardly tells Dr. Benton that they have a meeting planned for later that day. Tom is delighted to find out that his meeting is with Adam’s new girlfriend.

The three of them sit down to chat. As Tom asks her about her research, Adam rephrases it to help Olive organize her thoughts when he sees that she’s struggling to come up with an answer. Olive then tells Tom about her research on biomarkers in order to more easily and cheaply diagnose pancreatic cancer. As Tom inquires about her reasons for doing her research, Olive reluctantly admits that it’s because her mother had pancreatic cancer.

Finally, Tom asks Olive to spend two weeks writing up a report on the current state of her research. He says that he’ll make a determination of whether to give her the lab space and cover her research expenses depending on what he reads in that report.

When Tom steps away, Olive and Adam discuss that if she decides to go to Harvard then she needs to keep it a secret until the end of their arrangement, otherwise it’ll make Adam look worse. They also agree not to tell Tom that they’re only fake-dating.

The next day, Olive attends a well-attended talk that Tom is giving on campus. The auditorium is so packed that there’s no space anywhere. Anh convinces Olive to sit in Adam’s lap for the duration of the talk.

Afterwards, Olive and Anh head back to the biology building. Olive talks about the report she’s preparing for Tom and the presentation she needs to work on for a conference (the “SBD Conference”) coming up in Boston. Meanwhile, Anh is working on organizing an outreach event for BIPOC women in STEM for the conference.

As they walk back, they see that there’s a traffic jam involving a stopped car blocking an exit. Then they see Cherie , the department secretary, talking to Adam. Adam then proceeds to physically push a car out of the way to relieve the jam. Anh encourages Olive to go over and give him a kiss for his efforts. After some awkward negotiation with Adam, they kiss.

Olive is working on her report for Tom when Greg Cohen , one of Dr. Aslan’s other Ph.D. candidates, barges in, clearly agitated. Chase , another one of their lab mates, walks in uneasily after him. When Olive asks Greg what’s wrong, he angrily responds that Carlson is on his dissertation committee and he failed his proposal. They ask Olive whether she knew he was going to fail Greg, and Olive insists she didn’t know. Greg then yells at Olive and calls her selfish for not caring how Adam makes everyone’s lives miserable. Greg then storms off.

Later that day, Olive texts Adam. She asks him about failing Greg. She argues that he should be nicer, but Adam is unapologetic. He insists that his job is to make sure that students produce useful research. Olive gets frustrated texts profanity at him, and he doesn’t respond.

A few days later, Olive is on her way to the biosciences picnic, where she’ll be seeing Adam after their tense exchange. She, Anh, Jeremy and Malcom go together and are quite late. When they arrive, they see Adam playing Ultimate Frisbee shirtless, showing off his six-pack. Olive is surprised to find herself “viscerally attracted” to Adam.

As they put on sunscreen, Anh gives Olive way too much sunscreen. Meanwhile, the frisbee from the game lands near her. When Adam comes over to retrieve the frisbee, Anh offers Olive’s excess sunscreen to Adam. He accepts, and Olive rubs the sunscreen on him. Olive also apologizes for what she texted him the other day.

Tom then comes over and brings up that Adam will be going to Boston soon for a few days.

Olive is in the break room at night when she runs into Adam next. Olive is working on her report for Tom, but there’s a section she’s having trouble with since her lab equipment seems to be messing up. They chat and share snacks. Olive finds herself wondering why he’s single.

Olive also finds herself telling him about her mother and her death. She describes how, when she was 15, her mother was diagnosed with pancreatic cancer too late and only had a few weeks left to live by then. Olive also says that her father was never in the picture and her grandparents were deceased, so she was sent into the foster system until she was emancipated at 16.

When she mentions needing to get back to work, Adam offers to let her use his lab equipment if she needs it. He also gives her some advice on the Western blot she’s working with to make sure she’s doing it correctly. Before Olive leaves, she asks Adam why he’s single, but before he can really answer, Jeremy walks in and interrupts them.

On Saturday, Olive sends in her report to Tom. He responds by asking her to meet to talk about it at Adam’s house (where he’s staying) on Tuesday before he leaves for Boston. At Adam’s house, she and Tom chat about her report for about 20 minutes. Before she leaves, Tom offers her a spot at Harvard for the next year, and Olive is thrilled.

Adam gives her a ride back to campus. He talks about how excited he is about the research he and Tom are working on. As they chat, Adam says something that The Guy she’d met in the bathroom all those years ago had said to her. Olive realizes then that Adam was The Guy she’d met. She marvels at how she’d wondered about The Guy for years. Olive then suggests that go celebrate her lab spot and him and Tom’s grant.

They agree to get coffee. Before then, she convinces him to go with her to get flu shots at the setup on campus, all the while she teases him for his fear of needles.

On Wednesday, Olive and Adam are texting and teasing each other when Anh comes in and comments on how in love with Adam she is. Anh says that she feels better about dating Jeremy, since she sees how much Olive likes Adam. As Anh leaves, it dawns on Olive that Anh is right.

Olive soon texts Malcolm asking to talk. When they get together, she tells him about how she thinks she’s fallen for Adam. She also tells him that she thinks that Adam was The Guy that she met all those years ago. Malcolm suggests that perhaps Adam feels the same way. Olive doesn’t think that’s the case, but moreover, she says scared of being vulnerable and possibly giving up the friendship she and Adam currently have if she’s wrong. Olive also says that everyone she cares about ends up leaving her — citing her mother, father and grandparents.

Olive says she’s certain she doesn’t want to say anything to Adam about her feelings — but then she turns around and sees Adam standing there.

When Adam acknowledges that he overheard her, Olive quickly lies and said she was talking about some other guy she has a crush on. Their conversation is interrupted by Dr. Holden Rodriguez , who is going to Boston with Tom and Adam. Dr. Rodriguez knows Olive since he was on her graduate advisory committee her first year.

As they talk, Holden explains that he and Adam are old friends. They grew up together because their parents were all diplomats. Holden tells Olive about how his boyfriend dumped him just before prom, so Adam went as his date instead.

After Holden leaves, Adam comments that Holden speaks highly of Olive and her research. Adam also explains a comment Holden made about Tom, saying that the two don’t really get along. He then tells Olive that she should just tell Jeremy how she feels, incorrectly assuming that the mystery crush Olive was referring to is Jeremy.

Malcolm continues trying to convince Olive to admit her feelings to Adam, but Olive refuses. With Adam out of town, she feels his absence. When Adam finally texts her on Sunday, she feels even worse about her stupid lie about liking someone else.

On campus, she runs into Holden, who mentions how glad he is that Adam and Olive got together. Holden days that Adam had talked about someone he wanted to ask out for years, and he’s glad Adam finally did it. When he says that, Olive thinks about how there must be someone else out there that Adam likes, then, since they only really met a couple weeks ago.

Holden also warns her to watch out when it comes to Tom and to watch Adam’s back, since he doesn’t trust Tom.

A little later, Olive is informed that her research has been accepted for the SBD conference as a panel presentation with faculty. Olive feels overwhelmed, since graduate students very rarely are selected for oral presentations. She goes to her advisor, Dr. Aslan, and explains that she’s terrible at talking. Of course, Dr. Aslan just gives her some encouragement and tells Olive she’ll help her practice her presentation.

Afterwards, Olive tells Malcom and Anh, who also volunteer to help her practice. They also mention, however, that they each got invited to stay with people in Boston for the conference (Anh with Jeremy and Malcolm with some friends who had a spare room), so they won’t be rooming with Olive. Anh says she figured Olive would stay with Adam.

Olive is trying to sort out some living arrangements for Boston when Adam, who is back in town now, comes up to her. She tells him about having trouble finding accommodations in Boston. Adam comments that there’s probably not anything left in the vicinity by now, but she could stay in his room at the conference center. He adds that he has the room for the whole conference, but he will only be using the room two nights, so they’ll only overlap for one night most likely.

When she tells him about her presentation, he offers to look over her slides. She also invites him to her talk, and she thinks about how one of the reasons she likes him is that she always feels like he’s on her side.

At the hotel in Boston, Olive takes the empty bed, and she rehearses the talk she’s about to give in a few hours. When Adam arrives, she thanks him for all the help he gave regarding her presentation.

He asks when her presentation is so he can attend, but it turns out it overlaps with the Keynote speech, which he is giving along with two other people. She offers to show him the recording of it afterwards.

When Olive goes to do her panel presentation, she sees that Tom is on the same panel. She gives her portion of the talk, and it goes well. Malcolm and Anh are there to cheer her on.

Afterwards, the room empties out, and it’s just her and Tom. As they talk, she notices him moving closer until he tries to kiss her. When she pushes him away, he keeps trying. Finally, he says that she’s clearly someone who sleeps around to get ahead, and so they both know she’ll sleep with him, too, for the same reason. He also says that she only got on this panel because someone wanted to kiss-up to Adam Carlson.

He also says that Adam is the reason he accepted Olive into his lab. When Olive threatens to tell Adam about this, he says that Adam won’t believe her word against his. Olive also says she won’t go work in his lab, but Tom says she knows it’s the best option for her, and if she doesn’t then he’ll just replicate her research since he already knows all about it.

When Adam gets back to the hotel, Olive is crying. She tries to pretend nothing is wrong, but fails at it. Finally, she lies and tells him that she’s upset because she overheard someone saying that her research was “derivative” and that she was only chosen because of Adam.

Adam comforts her, and then he says he has an idea for where they should go instead.

Holding her hand, they walk past all the people at the department social and instead head out to dinner. Adam asks what she wants to eat, and Olive sees an all-you-can-eat sushi place and wants to go.

After dinner, as they head back, Olive’s heels are hurting her, so Adam gamely picks her up and brings her to their room. She then suggests that they watch a movie. Olive goes to grab a quick shower, and Adam offers her a t-shirt since she forgot to pack pajamas.

When Olive’s mind wanders back to being called mediocre (by Tom, though she doesn’t tell Adam that), Adam tells her about how his advisor had once told him he wouldn’t amount to anything because of a mistake he made. He says that he had started preparing applications for law school as a result, since the comment shook his confidence. However, Holden and Tom (who also trained under the same advisor) convinced him to stick with science.

Adam says that later he realized that his advisor was abusive and a bad mentor who created a toxic environment. Comparatively, Adam says that he is critical since he wants students to be better, but it isn’t about belittling them as people or cutting down their self-worth. Adam also says that no one ever reported his advisor’s behavior because he was short-listed for a Nobel Prize, and they didn’t think anyone would listen. Adam also mentions how Tom had helped mediate thing with him and his advisor, so he was grateful to Tom for that.

Adam then tells Olive that the abstracts submitted to SBD go through a blind review process, so they definitely didn’t choose her because of him.

Finally, Olive moves to kiss Adam, but before anything can happen, he stops her. He points out that she’s upset and staying in his room and that the situation feels coercive to him. When Olive says she’s fine, he points out that she said she was in love with someone else and that he doesn’t want to regret this later.

Olive convinces him that she’s fine with the situation, and soon things get intimate.

They have sex.

Afterwards, Olive asks Adam about a book he’s reading. He says it’s in Dutch and that he learned it as a kid. He also says that his parents were busy all the time and that he was mostly raised by au pairs. They then talk more about their childhoods.

As they chat, Adam finally tells Olive that he might be going to Harvard. The reason he’s leaving the conference early is to go interview with them. He thinks that working together with Tom in the same lab would make them much more productive. He also mentions that he could show her around Boston when she’s there.

Olive wakes up to a barrage of texts from Anh and Malcolm. When she finally talks to them, it turns out the Malcolm hooked up with Holden at the department social. Malcolm also says that Holden mentioned that Adam’s funds had been released (though Adam hadn’t mentioned it to Olive).

That night, Olive meets up with Adam. He wants to go out and have dinner, but Olive breaks things off with him, since she doesn’t know what to do about the Tom situation. She thinks that taking herself out of the equation is the best thing for him.

As she starts to leave, they end up kissing, but he pulls away, and she leaves.

Olive spends the next day crying. Then, determined not to send up at Harvard, Olive takes Adam’s advice to reach out to people through her advisor and asks Dr. Aslan to e-mail various people she’d met at the conference to see if they’d be interested in her research.

Dr. Aslan agrees, and also asks to see her speech. As Olive edits the video recording, Malcolm talks about how he went on a first date with Holden, but they ended up running into his entire family (since they are all science junkies who attend science conferences).

As she’s editing, Olive realizes she recorded her upsetting conversation with Tom. Malcolm and Anh hear her listening to it. Once they’ve listened to the whole thing, they insist that Olive needs to tell Adam about it. Finally, Malcolm fills Anh in on what was really going on with Olive and Adam. However, they both agree it’s clear that Olive has feelings for Adam and that Adam would want to know about this. Still, Olive knows how important the collaboration with Tom is to Adam, and she is reluctant to complicate things for him.

They decide to call Holden to ask for advice. Olive asks Holden what he thinks about Adam moving to Boston and working with Tom. Holden says that he doesn’t trust Tom. He says he thinks there was a weird dynamic where Tom was secretly sabotaging Adam during grad school and then defending him. He thinks that Tom likes Adam’s loyalty towards him and having influence over him. Holden also tells them that he thinks Tom and Adam’s collaboration benefits Tom more than Adam. Finally, Holden implies that he thinks the only reason Adam is considering leaving Stanford is because Olive is going to Harvard.

Olive tracks down Adam’s location at a dinner with some Harvard people, including Tom. When he sees her, he gets up and asks what’s wrong. Tom comes over to try to get Adam to sit back down, but Adam insists on talking to Olive. Finally, Olive starts playing the video. Adam grows furious as he realizes what happened. He tells Tom that he’s going to kill him and goes after him, but Olive tells Adam that he’s not worth it.

As the Harvard people demand an explanation, Adam ignores them and kisses Olive. He then tells Olive to send him the recording immediately and then goes to talk to the Harvard people.

A few days later, Olive is back home, and Adam is on his way back to San Francisco. Meanwhile, Olive has received responses from four cancer researchers who are all interested in her research.

When Adam gets back, Holden insists on a double date. Adam reluctantly agrees. When they all sit down, they address the fact that Malcolm still has misgivings about Adam because of Adam’s harsh criticism of his work. Adam tells Malcolm that it wasn’t personal.

As they joke around about pumpkin spiced flavored foods, Holden mentions how Adam has liked Olive for years. Olive corrects him, saying they’ve only been dating for a few weeks, but Holden says that they met three years ago and that he’s liked Olive ever since. Olive then realizes that Adam was definitely the The Guy (from three years ago) and that he did remember her.

After dinner, Olive and Adam head home. Adam tells Olive that Harvard is going to fire Tom and that there will be other disciplinary actions. Olive then tells Adam that she remembered him, too, from all those years ago. But she didn’t piece it together until later, and she admits that she didn’t say anything once she figured it out.

Finally, she tells him that she loves him (in broken Dutch).

Ten months later, it’s the 1-year anniversary of their first kiss. Olive and Adam go to the lab and recreate and their kiss at precisely the same time as last year.

As a third-year Ph.D. candidate, Olive Smith doesn't believe in lasting romantic relationships--but her best friend does, and that's what got her into this situation. Convincing Anh that Olive is dating and well on her way to a happily ever after was always going to take more than hand-wavy Jedi mind tricks: Scientists require proof. So, like any self-respecting biologist, Olive panics and kisses the first man she sees.

That man is none other than Adam Carlsen, a young hotshot professor--and well-known ass. Which is why Olive is positively floored when Stanford's reigning lab tyrant agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire, putting Olive's career on the Bunsen burner, Adam surprises her again with his unyielding support and even more unyielding...six-pack abs.

Suddenly their little experiment feels dangerously close to combustion. And Olive discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

For Chapter 16, I think it’s important to include the part where Olive comes out to Adam as demisexual. But other than that this is a great summary.

this book is so good i couldn’t put it down. the only i wish is it was both POVS i would of loved to see what adam was thinking during all of this or have his thoughts on when they met each other during the bathroom scene. and i would of loved to see him actually hurting tom for saying that stuff to olive.

The love hypothesis, by ali hazelwood.

This was initially pitched to me as “academic Kylo Ren and Rey fanfic,” and I was sold. Temporarily putting aside any and all feelings about The Last Jedi and The Rise of Skywalker and about the ~actual~ relationship or lack thereof between Rey and Kylo Ren in the movies, I absolutely loved this. 

The novel told the story of Olive, a PhD student who is working to cure cancer, and Adam-Carlsen-Not-Driver, the gruff and brooding advisor in the department who has a reputation for being tough and unfriendly. After an attempt to convince her best friend Anh that she’s seeing someone goes awry, Olive and Adam enter into a fake-dating agreement, and at this point, you can probably guess where the story is going.

This was freakin’ adorable. I’m a sucker for a good fake dating trope, I’m a sucker for Star Wars, and just the sheer level of cuteness that was present in this book was too much for me. Adam-Not-Driver is a brooder in the best Darcy-esque way, and Olive had such a loving personality that made you just want to give her a hug…or rather, for Adam to give her a hug. As much as I love Star Wars , and as much as I loved the little nods Hazelwood made to this story’s origins (Adam being the overlooked child of a diplomat, anyone? and let’s not look over this cover art!), the characters held up on their own. Additionally, I thought Hazelwood masterfully wove trope after trope into the story, giving Olive an awareness of her position in a romance novel-y story itself that added both depth and comedic value, as well as some measure of realness:

“Adam.” She rubbed her forehead with her fingers. “There will only be one bed.” 

He frowned. “No, as I said it’s a double–” 

“It’s not. It won’t be. There will only be one bed, for sure.”

He gave her a puzzled look. “I got the booking confirmation the other day. I can forward it to you if you want, it says that–” 

“It doesn’t matter what it says. It’s always one bed.”  

In terms of drawbacks, my qualms are minimal. While I didn’t love the hefty age gap/power gap, I appreciated the fact that it was addressed within the story and it wasn’t too overwhelming given that Olive didn’t work directly under Adam. I also really wish there was more at the end, though as you’ll notice, that’s something of a trend for me – while there were cute moments scattered throughout, I wished there had been more pages and more story after the Tom debacle. Even though I’m sad there wasn’t, I’m willing to acknowledge that that’s the sign of a truly good book. 

If you love Star Wars (or don’t), are a fan of academic romances and happily-ever-afters, or love a brooding Darcy character, this is the one for you.

Aaaand with that, I’m excited to give The Love Hypothesis a solid 5/5 stars and the power of my full recommendation.

Summary and Study Guide

The Love Hypothesis by Ali Hazelwood (2021) follows a female scientist’s comedic journey to true love that’s fraught with lies, tears, and awkward moments. The book was an instant NY Times bestseller, a BuzzFeed Best Summer Read of 2021, and Goodreads Choice Awards finalist. Born in Italy, Ali Hazelwood moved to the United States via Japan and Germany to pursue a Ph.D. in neuroscience. She currently works as a college professor and writes romance novels about women in STEM fields. The Love Hypothesis was her debut novel. This guide follows the 2021 Berkley edition.

Plot Summary

The Love Hypothesis is set in modern-day America and follows Olive Smith , a 26-year-old graduate student of biology at Stanford University. Olive’s research focuses on pancreatic cancer, but each chapter begins with a hypothesis about Olive’s love life or choices as is relevant to the chapter’s contents.

Two years before the main events of the story, Olive’s expired contacts act up right before her interview for Ph.D. candidacy at Stanford. While she waits in the bathroom for her eyes to stop watering, she meets Adam Carlsen , one of the foremost biology researchers in the world—though she doesn’t learn it was him until the end of the book. His wise words convince Olive that grad school is the right path, and two weeks later, she accepts an offer to study at Stanford.

Almost three years later, Olive is trying to convince her best friend that she’s over her ex-boyfriend so her friend, who is interested in her ex-boyfriend, will date him. Olive is working in the lab on a night she said she’d be on a date when she sees her friend walk by. Desperate to appear on a date, Olive kisses the first man she sees, who turns out to be Adam. Adam has a reputation for being mean and terrifying, and he demands an explanation. Olive haltingly explains her situation, apologizes for the kiss, and runs away, hoping she never sees him again.

A few days later, Olive’s friend corners her in the lab. Before Olive can spin an explanation, Adam arrives and acts warmly toward her, which convinces Olive’s friend their relationship is genuine. Olive wants to keep up the charade until her friends are solidly together, and Adam needs to convince Stanford he’s not leaving to get his research funds unfrozen. The two decide to pretend they’re dating for a month in hopes their fake relationship will be mutually beneficial.

Olive’s area of focus is early detection for pancreatic cancer. Her mother died from pancreatic cancer because it was found too late, and Olive dedicates her life to the disease so other people don’t lose loved ones to it. Needing a better equipped lab for the next phase of her research, Olive contacts several professors at other universities, but only one responds—Tom Benton from Harvard. He’ll be visiting Stanford in a couple of weeks, and Olive frantically works on her project in the hopes he’ll give her space in his lab.

Meanwhile, she keeps up appearances with Adam, meeting him at the campus coffee shop once a week. At their second fake date, Tom Benton joins them. It turns out that he’s a friend of Adam’s and wants to meet this girlfriend everyone’s been talking about. After listening to her research pitch, Tom requests a report by the end of the week, which Olive delivers. A few days later, Tom offers her a spot in his lab next year.

Olive receives an email regarding a paper she submitted to an upcoming conference in Boston. Her paper was accepted for a panel, which means she’ll need to give a speech. She’s terrified, but Adam helps her prepare until she feels more ready. Olive’s friends found other accommodations for the conference, which leaves Olive to share Adam’s hotel room. Olive’s panel overlaps with the keynote speech, and Adam is the keynote speaker, which means he won’t be able to attend as he promised he would.

After the panel, Tom approaches Olive and forces himself on her. When Olive pulls away and threatens to report him, Tom threatens to publish her research under his name and insults her, calling her mediocre and talentless. Adam finds Olive crying in their hotel room. Olive tells him what happened but not who insulted her. They spend the evening together. He shares a similar story from his grad school years, and they make love.

Olive spends the next few days dealing with her emotions, breaking things off with Adam because she feels it’s the right thing to do. When she finally meets up with her friends, they hear Tom’s insults, which Olive accidentally recorded after the panel. They convince Olive to tell Adam the truth and report Tom. Tom is fired from Harvard, and Olive and Adam get back together. Olive finds a new lab placement closer to Stanford, and the two stay in California together.
