APPLE BOOKS REVIEW

This adorkable fake-dating romance set in the world of academia might just be one of our favorite reads of the year. Biologist Olive Smith is too busy with the third year of her PhD program to worry about romance, so she’s fine when her ex and her best friend hook up. They feel guilty about it, though, and determined to see her best friend happy, Olive enters into a fake relationship with campus grump Dr. Adam Carlsen to prove just how over her ex she is. Little does Olive know that the curmudgeonly Adam has been secretly pining for her. Ali Hazelwood’s book is full of delightful tropes and a great sense of humor. The opposites-attract chemistry between stoic Adam and sunshiny Olive left us grinning from ear to ear.

PUBLISHERS WEEKLY JUN 7, 2021

Hazelwood debuts with a charming, offbeat rom-com pairing a somewhat awkward doctoral candidate with a hotshot young professor. Olive Smith, a third-year PhD student in biology at Stanford University, doubts that happily ever after exists, while her bestie, Anh, is a hopeless romantic. But Olive briefly dated Anh's current crush, Jeremy, and now Anh's refusing to act on her feelings because of "girl code." In an attempt to prove she's over Jeremy and alleviate Anh's guilt, Olive impulsively kisses famously irascible professor Adam Carlsen and convinces him to "fake-date" her. But as attraction and chemistry grow, their relationship becomes more than pretense. Things further evolve after Olive is harassed and belittled at a professional conference and Adam provides a supportive shoulder. But can their relationship hold up in the real world? With whip-smart and endearing characters, snappy prose, and a quirky take on a favorite trope, Hazelwood convincingly navigates the fraught shoals of academia. The delightful supporting characters, especially Adam's colleague Holden Rodriquez and Olive's friends Malcolm and Anh, add flavor—and readers will love seeing the villain of the story dispatched in appropriate fashion. This smart, sexy contemporary should delight a wide swath of romance lovers.

Customer Reviews

Amazing read.

I absolutely love this book! It’s funny, romantic, angsty, sexy, and offers the public a look into the absolutely draining (yet partially rewarding) life as a STEM grad student. Love the diversity and the message about the hardships marginalized grad students face in the cis-white-male dominated world of academia!

Such sass and much cuteness

Oh my god. I loved it. So much. Holy crap. The banter. The snark and the relationship dynamo between the main characters. Everything I could have hoped for. Get it. Get it. Get it. Devoured this book in a day.

STEM representation!!!

This book was every STEM girls dream 🤩 the man was smart and hot, supported the main lead, and the main lead was a strong independent woman but i lovedddd the progression and flow of this book. Also how it talked about such important aspects of STEM both good and bad. Definitely a good read!!! :)

The Love Hypothesis (Review, Recap & Full Summary)

By ali hazelwood.

Book review, full book summary and synopsis for The Love Hypothesis by Ali Hazelwood, a delightful rom-com about a fake relationship between a biology Ph.D. student and a professor.

In The Love Hypothesis , Olive is a third-year biology Ph.D. candidate who shares a kiss with a handsome stranger in order make her friend think that she's in a relationship. She's horrified when she realizes the "stranger" is Dr. Adam Carlson, a prominent professor in her department who is known for being a hypercritical and moody tyrant.

She and Adam each have reasons for needing to be in a relationship, and they agree to pretend to date for the sake of appearances. Of course, as she gets to know Adam, it's only a matter of time before she starts feeling something for him, and it becomes clear that her little experiment in fake-dating just might combust...

(The Full Plot Summary is also available, below)

Full Plot Summary

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.

Book Review

The Love Hypothesis by Ali Hazelwood came out a few months ago, and I didn’t really pay much attention to it. However, people seem to really be enjoying this book, and after reading The School for Good Mothers , I was really in mood for something light and fun.

In the Love Hypothesis, Olive is a third-year biology Ph.D. student at Stanford who ends up fake-dating a young and handsome tenured professor in her department. All the usual rom-com shenanigans ensue.

The Love Hypothesis is an unapologetically cheesy rom-com novel — with an upbeat attitude, meet cutes, fake-dating tropes, etc. — but it’s also a genuinely fun and often funny book. It hits a lot of familiar notes if you’re familiar with this genre, but somehow Ali Hazelwood has arranged them in a way that ends up being delightful and entertaining.

The book is super melodramatic at parts, uses so many tropes I couldn’t even list them all here if I was inclined to do so and is predictable in the way that rom-coms are always kind of predictable. That all said, I still had a fantastic time reading it and it flew by.

This is a short review because honestly it’s not that complicated to explain that this book is super cheesy and super fun.

Read it or Skip it?

If you like “chick lit” and rom-coms, you should definitely look into this book. I tend to be a little hypercritical of books in this genre, but I really enjoyed The Love Hypothesis . I found myself smiling and chuckling quite a bit as I read it.

This book is a straight-up cheesy rom-com — it is funny, melodramatic and fun as hell. I thought it was great.

Narrated by : Callie Dalton Length : 11 hours 8 minutes

I listened to about half of this on audiobook. I think the audiobook is solid. The narrator is easy to listen to and does a good job with it.

'The Love Hypothesis' won Amazon's best romance book of 2021, has a near-perfect rating on Goodreads, and is all over TikTok. Here's why it's such a unique love story.

• " The Love Hypothesis " grabbed the attention of romance readers everywhere in 2021.
• It was named Amazon's Best Romance Novel of 2021 and was nominated for a Goodreads Choice Award.
• This book checks off all my boxes for a great romance read and is definitely worth the hype.

This year, Amazon named " The Love Hypothesis " by Ali Hazelwood the best romance book of the year. Even though it was only recently published in September 2021, "The Love Hypothesis" has quickly become a fan-favorite, with 88% of Goodreads reviewers giving it four- or five-star-level praise .

It was also nominated for a Goodreads Choice Award and is hugely popular amongst Book of the Month members , with only 1% of readers giving it a "disliked" rating.

"The Love Hypothesis" is about Olive Smith, a third-year Ph.D. candidate studying pancreatic cancer at Stanford. In an attempt to convince one of her best friends that she's moved on from an old crush, she impulsively kisses Dr. Adam Carlsen, the department's notoriously brutal (but undeniably attractive) professor. After the kiss, Adam and Olive agree to fake a relationship so she can prove to her friend that she's happily dating and he can convince their department that he isn't planning to leave anytime soon.

I'm a little picky about my romance novels , so giving this read every bit of a five-star review didn't come lightly. My standards are high because the best romance novels have the potential to expose readers to authentic and imperfect relationships and offer new topics of discussion without making us feel like it's a story we've already read. 

With all the hype surrounding this new romance read, I couldn't resist picking it up.

Here's why "The Love Hypothesis" is one of my favorite recent romance books:

1. the story focuses a lot on olive and adam's lives outside their romance, making their love story more believable and interesting..

Romance novels tend to fall into a few popular tropes such as " enemies-to-lovers " or "forbidden love." "The Love Hypothesis" combines two of the most popular tropes right now, "Fake dating" and "grumpy/sunshine," really well — I loved the contrast between Adam's serious attitude to Olive's bright and sugary one. 

But despite following these tropes, the story feels fresh because it's also largely about Olive's work and its meaning to her. The only other romance book I've read featuring a STEM heroine is "The Kiss Quotient" , so I loved seeing that representation and learning about something new. 

The story honestly reflected the challenges Ph.D. candidates face in academia and that authenticity — deepened by the author's personal experiences — brought the characters, the settings, and the romance to life even more as Olive and Adam faced challenges with funding, time-consuming research, and questioning their sense of purpose.

2. The steamier scenes are also awkward and realistic, which made them even better.

In romance books, there are a few different levels of how graphic a steamy scene can get , from little-to-no detail to explicitly outlined movements. (I personally prefer mine to "fade to black.")

There was only one chapter with adult content, and it was definitely graphic. While I made a ton of ridiculous faces while reading and tried to skim past the parts that made me audibly gasp, I loved that it wasn't a movie-made, perfect sex scene with graceful movements and smooth dialogue. The scene was a little awkward, imperfect, and full of consent and conversation, making it refreshingly real.

3. The book deals with other topics besides the main love story, making it a much deeper read.

While it's wonderful to get swept up in the magic of a romantic storyline, having a secondary plot that addresses real issues is what makes a romance novel truly great . 

Mild spoilers and content warnings ahead: While "The Love Hypothesis" is a fun romantic read, it also addresses the pain of familial death, power differentials, intimacy challenges, and, most prevalently, workplace sexual harassment. 

Love is beautiful, fun, and amazing, but "The Love Hypothesis" takes the opportunity to also include conversations about serious issues. While these topics may be tough for some readers, I think these plot points, hard conversations, and complicated emotions take "The Love Hypothesis" to the next level and make it a five-star read. 

The bottom line

"The Love Hypothesis" has everything I personally look for in a romance novel: A unique storyline, authentic characters, and an important message. If you're looking for a perfectly balanced romance read, "The Love Hypothesis" is worth the hype and definitely one of the best romance books to come out in the past year.

About the author, excerpt. © reprinted by permission. all rights reserved..

Chapter One

Hypothesis: When given a choice between A (a slightly inconveniencing situation) and B (a colossal shitshow with devastating consequences), I will inevitably end up selecting B.

In Olive's defense, the man didn't seem to mind the kiss too much.

It did take him a moment to adjust-perfectly understandable, given the sudden circumstances. It was an awkward, uncomfortable, somewhat painful minute, in which Olive was simultaneously smashing her lips against his and pushing herself as high as her toes would extend to keep her mouth at the same level as his face. Did he have to be so tall? The kiss must have looked like some clumsy headbutt, and she grew anxious that she was not going to be able to pull the whole thing off. Her friend Anh, whom Olive had spotted coming her way a few seconds ago, was going to take one look at this and know at once that Olive and Kiss Dude couldn't possibly be two people in the middle of a date.

Then that agonizingly slow moment went by, and the kiss became . . . different. The man inhaled sharply and inclined his head a tiny bit, making Olive feel less like a squirrel monkey climbing a baobab tree, and his hands-which were large and pleasantly warm in the AC of the hallway-closed around her waist. They slid up a few inches, coming to wrap around Olive's rib cage and holding her to himself. Not too close, and not too far.

It was more of a prolonged peck than anything, but it was quite nice, and for the life span of a few seconds Olive forgot a large number of things, including the fact that she was pressed against a random, unknown dude. That she'd barely had the time to whisper "Can I please kiss you?" before locking lips with him. That what had originally driven her to put on this entire show was the hope of fooling Anh, her best friend in the whole world.

But a good kiss will do that: make a girl forget herself for a while. Olive found herself melting into a broad, solid chest that showed absolutely no give. Her hands traveled from a defined jaw into surprisingly thick and soft hair, and then-then she heard herself sigh, as if already out of breath, and that's when it hit her like a brick on the head, the realization that- No. No.

Nope, nope, no.

She should not be enjoying this. Random dude, and all that.

Olive gasped and pushed herself away from him, frantically looking for Anh. In the 11:00 p.m. bluish glow of the biology labs' hallway, her friend was nowhere to be seen. Weird. Olive was sure she had spotted her a few seconds earlier.

Kiss Dude, on the other hand, was standing right in front of her, lips parted, chest rising and a weird light flickering in his eyes, which was exactly when it dawned on her, the enormity of what she had just done. Of who she had just-

Fuck her life.

Fuck. Her. Life.

Because Dr. Adam Carlsen was a known ass.

This fact was not remarkable in and of itself, as in academia every position above the graduate student level (Olive's level, sadly) required some degree of assness in order to be held for any length of time, with tenured faculty at the very peak of the ass pyramid. Dr. Carlsen, though-he was exceptional. At least if the rumors were anything to go by.

He was the reason Olive's roommate, Malcolm, had to completely scrap two research projects and would likely end up graduating a year late; the one who had made Jeremy throw up from anxiety before his qualifying exams; the sole culprit for half the students in the department being forced to postpone their thesis defenses. Joe, who used to be in Olive's cohort and would take her to watch out-of-focus European movies with microscopic subtitles every Thursday night, had been a research assistant in Carlsen's lab, but he'd decided to drop out six months into it for "reasons." It was probably for the best, since most of Carlsen's remaining graduate assistants had perennially shaky hands and often looked like they hadn't slept in a year.

Dr. Carlsen might have been a young academic rock star and biology's wunderkind, but he was also mean and hypercritical, and it was obvious in the way he spoke, in the way he carried himself, that he thought himself the only person doing decent science within the Stanford biology department. Within the entire world, probably. He was a notoriously moody, obnoxious, terrifying dick.

And Olive had just kissed him.

She wasn't sure how long the silence lasted-only that he was the one to break it. He stood in front of Olive, ridiculously intimidating with dark eyes and even darker hair, staring down from who knows how many inches above six feet-he must have been over half a foot taller than she was. He scowled, an expression that she recognized from seeing him attend the departmental seminar, a look that usually preceded him raising his hand to point out some perceived fatal flaw in the speaker's work.

Adam Carlsen. Destroyer of research careers , Olive had once overheard her adviser say.

It's okay. It's fine. Totally fine. She was just going to pretend nothing had happened, nod at him politely, and tiptoe her way out of here. Yes, solid plan.

"Did you . . . Did you just kiss me?" He sounded puzzled, and maybe a little out of breath. His lips were full and plump and . . . God. Kissed. There was simply no way Olive could get away with denying what she had just done.

Still, it was worth a try.

Surprisingly, it seemed to work.

"Ah. Okay, then." Carlsen nodded and turned around, looking vaguely disoriented. He took a couple of steps down the hallway, reached the water fountain-maybe where he'd been headed in the first place.

Olive was starting to believe that she might actually be off the hook when he halted and turned back with a skeptical expression.

"Are you sure?"

"I-" She buried her face in her hands. "It's not the way it looks."

"Okay. I . . . Okay," he repeated slowly. His voice was deep and low and sounded a lot like he was on his way to get ting mad. Like maybe he was already mad. "What's going on here?"

There was simply no way to explain this. Any normal person would have found Olive's situation odd, but Adam Carlsen, who obviously considered empathy a bug and not a feature of humanity, could never understand. She let her hands fall to her sides and took a deep breath.

"I . . . listen, I don't mean to be rude, but this is really none of your business."

He stared at her for a moment, and then he nodded. "Yes. Of course." He must be getting back into his usual groove, because his tone had lost some of its surprise and was back to normal-dry. Laconic. "I'll just go back to my office and begin to work on my Title IX complaint."

Olive exhaled in relief. "Yeah. That would be great, since- Wait. Your what?"

He cocked his head. "Title IX is a federal law that protects against sexual misconduct within academic settings-"

"I know what Title IX is."

"I see. So you willfully chose to disregard it."

"I- What? No. No, I didn't!"

He shrugged. "I must be mistaken, then. Someone else must have assaulted me."

"Assault-I didn't 'assault' you."

"You did kiss me."

"But not really ."

"Without first securing my consent."

"I asked if I could kiss you!"

"And then did so without waiting for my response."

"What? You said yes."

"Excuse me?"

She frowned. "I asked if I could kiss you, and you said yes."

"Incorrect. You asked if you could kiss me and I snorted."

"I'm pretty sure I heard you said yes."

He lifted one eyebrow, and for a minute Olive let herself daydream of drowning someone. Dr. Carlsen. Herself. Both sounded like great options.

"Listen, I'm really sorry. It was a weird situation. Can we just forget that this happened?"

He studied her for a long moment, his angular face serious and something else, something that she couldn't quite decipher because she was too busy noticing all over again how damn towering and broad he was. Just massive. Olive had always been slight, just this side of too slender, but girls who are five eight rarely felt diminutive. At least until they found themselves standing next to Adam Carlsen. She'd known that he was tall, of course, from seeing him around the department or walking across campus, from sharing the elevator with him, but they'd never interacted. Never been this close.

Except for a second ago, Olive. When you almost put your tongue in his-

"Is something wrong?" He sounded almost concerned.

"What? No. No, there isn't."

"Because," he continued calmly, "kissing a stranger at midnight in a science lab might be a sign that there is."

"There isn't."

Carlsen nodded, thoughtful. "Very well. Expect mail in the next few days, then." He began to walk past her, and she turned to yell after him.

"You didn't even ask my name!"

"I'm sure anyone could figure it out, since you must have swiped your badge to get in the labs area after hours. Have a good night."

"Wait!" She leaned forward and stopped him with a hand on his wrist. He paused immediately, even though it was obvious that it would take him no effort to free himself, and stared pointedly at the spot where her fingers had wrapped around his skin-right below a wristwatch that probably cost half her yearly graduate salary. Or all of it.

She let go of him at once and took one step back. "Sorry, I didn't mean to-"

"The kiss. Explain."

Olive bit into her lower lip. She had truly screwed herself over. She had to tell him, now. "Anh Pham." She looked around to make sure Anh was really gone. "The girl who was passing by. She's a graduate student in the biology department."

Carlsen gave no indication of knowing who Anh was.

"Anh has . . ." Olive pushed a strand of brown hair behind her ear. This was where the story became embarrassing. Complicated, and a little juvenile sounding. "I was seeing this guy in the department. Jeremy Langley, he has red hair and works with Dr. . . . Anyway, we went out just a couple of times, and then I brought him to Anh's birthday party, and they just sort of hit it off and-"

Olive shut her eyes. Which was probably a bad idea, because now she could see it painted on her lids, how her best friend and her date had bantered in that bowling alley, as if they'd known each other their whole lives; the never-exhausted topics of conversation, the laughter, and then, at the end of the night, Jeremy following Anh's every move with his gaze. It had been painfully clear who he was interested in. Olive waved a hand and tried for a smile.

"Long story short, after Jeremy and I ended things he asked Anh out. She said no because of . . . girl code and all that, but I can tell that she really likes him. She's afraid to hurt my feelings, and no matter how many times I told her it was fine she wouldn't believe me."

Not to mention that the other day I overheard her confess to our friend Malcolm that she thought Jeremy was awesome, but she could never betray me by going out with him, and she sounded so dejected. Disappointed and insecure, not at all like the spunky, larger-than-life Anh I am used to.

"So I just lied and told her that I was already dating someone else. Because she's one of my closest friends and I'd never seen her like a guy this much and I want her to have the good things she deserves and I'm positive that she would do the same for me and-" Olive realized that she was rambling and that Carlsen couldn't have cared less. She stopped and swallowed, even though her mouth felt dry. "Tonight. I told her I'd be on a date tonight ."

"Ah." His expression was unreadable.

"But I'm not. So I decided to come in to work on an experiment, but Anh showed up, too. She wasn't supposed to be here. But she was. Coming this way. And I panicked-well." Olive wiped a hand down her face. "I didn't really think."

Carlsen didn't say anything, but it was there in his eyes that he was thinking. Obviously.

"I just needed her to believe that I was on a date."

He nodded. "So you kissed the first person you saw in the hallway. Perfectly logical."

Olive winced. "When you put it like that, perhaps it wasn't my best moment."

"But it wasn't my worst, either! I'm pretty sure Anh saw us. Now she'll think that I was on a date with you and she'll hopefully feel free to go out with Jeremy and-" She shook her head. "Listen. I'm so, so sorry about the kiss."

"Please, don't report me. I really thought I heard you say yes. I promise I didn't mean to . . ."

Suddenly, the enormity of what she had just done fully dawned on her. She had just kissed a random guy, a guy who happened to be the most notoriously unpleasant faculty member in the biology department. She'd misunderstood a snort for consent, she'd basically attacked him in the hallway, and now he was staring at her in that odd, pensive way, so large and focused and close to her, and . . .

Maybe it was the late night. Maybe it was that her last coffee had been sixteen hours ago. Maybe it was Adam Carlsen looking down at her, like that. All of a sudden, this entire situation was just too much.

"Actually, you're absolutely right. And I am so sorry. If you felt in any way harassed by me, you really should report me, because it's only fair. It was a horrible thing to do, though I really didn't want to . . . Not that my intentions matter; it's more like your perception of . . ."

Crap, crap, crap.

"I'm going to leave now, okay? Thank you, and . . . I am so, so, so sorry." Olive spun around on her heels and ran away down the hallway.

"Olive," she heard him call after her. "Olive, wait-"

She didn't stop. She sprinted down the stairs to the first floor and then out the building and across the pathways of the sparsely lit Stanford campus, running past a girl walking her dog and a group of students laughing in front of the library. She continued until she was standing in front of her apartment's door, stopping only to unlock it, making a beeline for her room in the hope of avoiding her roommate and whoever he might have brought home tonight. It wasn’t until she slumped on her bed, staring at the glow‑in‑the- dark stars glued to her ceiling, that she realized that she had neglected to check on her lab mice. She had also left her laptop on her bench and her sweatshirt somewhere in the lab, and she had completely forgotten to stop at the store and buy the coffee she’d promised Malcolm she’d get for tomorrow morning. Shit. What a disaster of a day. It never occurred to Olive that Dr. Adam Carlsen— known ass— had called her by her name.

Love Hypothesis Novel- My Honest Review

About the author

Ali hazelwood.

Ali Hazelwood is a multi-published author—alas, of peer-reviewed articles about brain science, in which no one makes out and the ever after is not always happy. Originally from Italy, she lived in Germany and Japan before moving to the U.S. to pursue a Ph.D. in neuroscience. She recently became a professor, which absolutely terrifies her. When Ali is not at work, she can be found running, crocheting, eating cake pops, or watching sci-fi movies with her two feline overlords (and her slightly-less-feline husband).

Chapter 20-Epilogue Chapter Summaries & Analyses

Chapter 20 summary.

Olive goes to the restaurant where Harvard’s biology department took Adam for dinner. She plans to surreptitiously get Adam’s attention and motion for him to check his phone before leaving, but he sees her immediately and leaves his dinner meeting to talk to her. Tom interrupts them, and Adam orders him to leave, his “voice low and cold” (324). Tom refuses to go, and Olive starts playing the recording of Tom’s insults.

Adam explodes with anger, threatening to kill Tom if he says anything else about “the woman [he] love[s]” and throwing him against the wall (326). Olive begs him to stop. He does and goes to her, comforting her before answering to the confused and angry Harvard professors. Adam says he will take care of everything with Harvard. When he’s done, he’ll find Olive and “take care of [her]” (327).
