Tawni’s Book Nook: The Love Hypothesis by Ali Hazelwood Book Review

Rating: ⭐️⭐️⭐️⭐️⭐️ 5/5

OMG, I loved The Love Hypothesis by Ali Hazelwood. This was easily a five star read for me. And as you’ll see throughout this book review, there’s a lot I loved about Olive and Adam’s story. I had read one of Ali Hazelwood’s short stories before, but this was my first time reading one of her full-length novels and my first real introduction to STEM romance.

And apparently, all I needed was a fake relationship, a bubbly Ph.D. student and a tall, brooding professor who secretly has a soft side to completely suck me in.

Dr. Adam Carlsen? Tall, brooding, intimidating and HOT.

Olive Smith? Sunshine, bubbly, sweet, smart and surprisingly relatable.

Fake dating? One of my favorite romance tropes. Right next to Friends to Lovers.

Banter, teasing and inside jokes? Give me all of it.

And the spice?

We’ll get to that.

But what surprised me most about The Love Hypothesis was that underneath all the things I already knew I loved about romance novels, there was something deeper about Olive and Adam’s relationship that really connected with me.

My First STEM Romance: The Love Hypothesis

Going into The Love Hypothesis, I wasn’t entirely sure what to expect from a STEM romance.

Olive is a Ph.D. candidate at Stanford, so science and academia aren’t simply used as a cute backdrop for the romance. Her research, lab work and career are important parts of her life and the story.

I’ll admit, some of the STEM jargon went a little over my head.

Science has never exactly been my strongest subject, so there were definitely moments when I basically accepted that Olive knew what she was talking about and kept reading.

But it never stopped me from enjoying the story.

Because while I might not understand every detail of Olive’s research, I absolutely understand fake dating.

Olive wants to convince her best friend that she has moved on from a previous relationship. So, in a moment of panic, she kisses the first man she sees.

Unfortunately, or perhaps very fortunately, that man happens to be Dr. Adam Carlsen.

And thus begins the fake dating.

You already have me.

Why I Connected With Olive

Olive was probably one of my favorite parts of this book because there were pieces of her personality that reminded me of myself.

She’s bubbly, sweet, smart and has this sunshine quality about her that makes her incredibly likable.

But she isn’t endlessly happy.

Underneath that bubbly personality, Olive also experiences loneliness, sadness and self-doubt. She can be optimistic and still have moments when she feels completely alone.

I loved that both sides of her were allowed to exist at the same time.

Sometimes a sunshine character can feel like she exists simply to brighten the grumpy man’s life. Olive didn’t feel that way to me. She has her own ambitions, insecurities, friendships and fears. She cares deeply about her research and her future, and she’s trying to figure out where she belongs.

That combination of bubbly and vulnerable made her feel much more real to me.

I found myself rooting for Olive beyond her relationship with Adam.

Although, obviously, I was VERY invested in that relationship too.

And Then There’s Adam Carlsen…

Like I said… Tall. Brooding. Intimidating. Brilliant. Hot.

Do I really need to continue?

Adam has the reputation you’d expect from the intimidating professor everyone seems terrified of. He’s blunt, serious and definitely isn’t walking around Stanford trying to win any popularity contests.

And yet, the more time Olive spends with him, the more we get to see another version of Adam.

That’s the version that got me.

Yes, I loved the grumpy/sunshine dynamic. And yes, I obviously found the whole tall, brooding professor thing attractive.

But what I really loved about Adam was the way he cares for Olive.

He pays attention to her.

Adam wants to take care of her and protect her. He makes sure she has what she needs, but he also cares about the things she simply wants.

Even when that thing is pumpkin-flavored “sludge.”

I loved the whole pumpkin drink thing because it seems so insignificant, but that’s exactly why it matters to me.

Adam doesn’t have to understand why Olive loves something he thinks is disgusting. He doesn’t have to like it himself.

He just knows she likes it.

There’s something incredibly romantic to me about someone remembering the little things that make another person happy.

It’s knowing someone’s coffee order. Remembering something they mentioned weeks ago. Making sure they’ve eaten. Noticing when something is wrong. Bringing them their favorite ridiculous pumpkin drink because you know it will make them happy.

Sometimes love is simply paying attention.

And Adam pays attention to Olive.

Fake Dating + Banter = Apparently My Weakness

Fake dating is easily one of my favorite romance tropes, right alongside friends to lovers.

There’s something so satisfying about watching two characters repeatedly insist that their relationship is completely fake while everyone reading the book is thinking:

Sure. Totally fake. Keep telling yourselves that.

But I realized while reading The Love Hypothesis that fake dating alone isn’t necessarily what makes the trope work for me.

I need the banter too.

I LOVE banter.

Give me the teasing, playful back-and-forth and especially the little inside jokes that slowly develop between two people.

There’s something intimate about reaching the point in a relationship where you know someone well enough to mess with them. You know what will make them laugh. You know how far you can push a joke. Eventually, you have references and jokes that might mean absolutely nothing to anyone else, but they mean something to the two of you.

Olive and Adam gave me that.

Their personalities play off each other so well. Olive has this bubbly warmth while Adam is much more serious and controlled. Watching them become increasingly comfortable with each other was one of my favorite parts of the story.

And I think I finally figured out why banter matters so much to me in romance.

I don’t only want to believe two characters are attracted to each other.

More importantly, I want to believe they actually like each other.

They should laugh together. Tease each other. Flirt. Be ridiculous. Have conversations that aren’t solely there to move the romance forward.

I want the relationship to feel like it could also be a friendship.

Give me that plus fake dating, emotional intimacy and sexual tension?

I’m invested.

Olive’s Vulnerability About Sex Hit Me Differently

There was one conversation between Olive and Adam that unexpectedly stopped me in my tracks.

Olive opens up about sex and attraction, explaining that she needs to genuinely trust and like someone before she experiences that kind of sexual attraction.

Her experience isn’t exactly the same as mine, but something about what she said made me think about my own experiences in a way I hadn’t before.

I’ve experienced attraction. I’ve had sex, and I’ve enjoyed sex.

But I don’t know if I’ve ever experienced sex while feeling completely secure in knowing the feelings between us were mutual.

I’ve been with men I was attracted to. Men I liked.

But did they genuinely like me in the same way?

Were they as attracted to me as I was to them?

Did they actually care about me beyond the physical relationship?

I don’t know.

And maybe that’s why I sometimes wonder if I’ve ever experienced sex to its fullest potential. Not necessarily because something physical was missing, but because the emotional connection and security may have been missing.

There’s a difference between knowing someone wants to have sex with you and feeling like someone genuinely wants you.

They like you.

They’re attracted to you.

They care about you.

Maybe they even love you.

And most importantly, you don’t have to constantly question whether those feelings are mutual because they’ve made you feel secure enough to know they are.

That’s what made Olive’s vulnerability with Adam feel so intimate to me.

She isn’t simply deciding she wants to have sex with him. She’s acknowledging that she trusts him. She likes him. She wants him.

For Olive, those things are connected.

And maybe that kind of connection is something I’m still waiting to experience too.

Okay, NOW Let’s Talk About the Spice 🌶️

OMG.

The spice.

After spending so much of the book watching the tension between Olive and Adam build, I needed the payoff to be worth it.

And for me?

It absolutely was.

I’ve realized as I’ve read more romance novels that I need some level of spice in my romance.

That doesn’t mean I want an entire book to revolve around sex. I don’t. I still need an actual story with characters I care about. There also needs to be chemistry, tension and emotional development.

But when I’m reading romance, physical intimacy is part of what makes the relationship feel complete for me.

And after thinking about Olive’s vulnerability around sex, I think I understand a little better why.

The spice in The Love Hypothesis works for me because the emotional relationship is already there.

By the time Olive and Adam cross that line, I don’t just want two attractive characters to hook up.

I want Olive and Adam to finally go there.

I’ve watched them tease each other, care for each other, trust each other and slowly become more important to one another.

The physical relationship feels like another layer of a connection I’m already invested in.

So when all that tension finally pays off?

YES.

I thoroughly enjoyed it.

No further notes. 🌶️🔥

The Love Hypothesis Is More Than Just a Romance

As much as I loved Olive and Adam together, The Love Hypothesis also gave me enough story outside of their relationship to keep me interested.

Olive has goals that have nothing to do with Adam. Her research matters to her. So do her friendships and her future.

The book also gets into some heavier issues involving academia, professional power dynamics and what can happen when someone with more influence takes advantage of that imbalance.

Those storylines gave the novel more substance than I expected.

I wasn’t simply waiting for the next romantic interaction between Olive and Adam. I genuinely needed to know what was going to happen to Olive.

That’s usually one of my biggest signs that a book has me hooked. I’ve talked before about when I decide to DNF a book, but The Love Hypothesis gave me the exact opposite problem. When “one more chapter” somehow turns into five more chapters, we have a problem.

And that happened a lot with this one.

So, Did The Love Hypothesis Live Up to the Hype?

For me, absolutely.

I loved Olive. I loved Adam. Their chemistry, banter and fake dating completely worked for me. More than anything, I loved watching their relationship slowly become something neither of them could convincingly call fake anymore.

And, yes, I loved the spice.

Was every bit of STEM jargon easy for me to understand?

Definitely not.

But it didn’t need to be. I understood enough to follow Olive’s world, and the scientific setting made the book feel different from other contemporary romances I’ve read.

More importantly, I cared about these characters.

When I think about everything I loved about Olive and Adam, I keep coming back to one thing:

They don’t just want each other. They genuinely like each other.

There’s physical attraction and sexual chemistry, but there’s also friendship, teasing, trust, comfort, laughter and care.

Adam notices Olive.

He listens to her.

Adam remembers the little things about her.

And he wants to take care of her.

And Olive gradually reaches a place where she trusts him enough to be completely vulnerable with him.

Apparently, give me all of that plus fake dating, grumpy/sunshine, banter and some good spice, and you’ve pretty much figured out the formula for making me love a romance novel.

I finished The Love Hypothesis completely understanding why so many readers love Ali Hazelwood.

In fact, I loved it so much that I was ridiculously excited to immediately watch the movie adaptation.

Unfortunately…

We need to talk about that.

The Love Hypothesis Book vs. Movie

Let me start by saying that I understand a movie adaptation cannot include everything from a book.

Characters will be cut. Scenes will be shortened. Storylines will be combined. Things will happen in a different order.

I expect that.

My problem with The Love Hypothesis adaptation wasn’t simply that things changed.

The entire movie felt rushed.

That was my overwhelming feeling while watching it.

A lot of the recognizable scenarios from the novel are still there, but some happen differently, some happen in a different order, some are condensed and others are missing completely.

And so much of the context seemed to disappear along with them.

Instead of feeling like I was watching Olive and Adam’s relationship naturally develop, there were times when it felt like the movie was rushing from one recognizable book moment to another.

Here’s a scene readers will recognize.

Okay, next.

Here’s another one.

Moving on.

The major pieces of the story might be there, but the moments between those pieces were exactly what made me fall in love with the book.

The novel gives Olive and Adam time to become Olive and Adam.

We get the conversations. The teasing. The inside jokes. The recurring interactions. The moments when Adam quietly takes care of Olive. The gradual shift from awkward fake dating to something that feels increasingly real.

Those interactions aren’t filler.

They’re relationship development.

When you remove too many of them, you might still arrive at the same major romantic moments, but those moments don’t necessarily carry the same emotional weight.

And that’s what I felt while watching the movie.

And Where Was Dr. Holden Rodrigues?!

This was probably one of the most surprising omissions for me.

Holden isn’t even in the movie.

I understand cutting minor characters when adapting a novel, but Holden didn’t feel insignificant enough for me to completely remove him.

He’s Adam’s longtime friend, which means he gives us another perspective on Adam.

Everyone at Stanford seems to know the intimidating Dr. Carlsen. Holden knows Adam.

That distinction matters because part of what I loved about Adam’s character was slowly discovering the person underneath that intimidating reputation.

Removing Holden also means losing other pieces of the story connected to him, including his relationship with Malcolm.

Could the central Olive and Adam romance still exist without Holden?

Of course.

But I missed him.

And his absence was another example of how much context seemed to disappear in the process of condensing the novel into a movie.

The Movie Made Me Realize How Much the Little Moments Mattered in The Love Hypothesis

This was probably my biggest takeaway from the adaptation.

Recreating a memorable scene from a book isn’t necessarily the same as recreating what made that scene special.

Because sometimes the scene itself isn’t the important part.

It’s everything that happened before it.

By the time the bigger romantic and intimate moments happen in the book, I’ve spent all this time with Olive and Adam.

I understand Olive’s insecurities.

I’ve watched Adam quietly care for her.

Their banter has developed right alongside their relationship.

Over time, I’ve watched Olive become increasingly comfortable with him.

I understand why trusting Adam matters to her.

So when something finally happens between them, it feels earned.

The movie can recreate a kiss, a conversation or another recognizable moment from the novel, but if you remove too much of the buildup, it doesn’t necessarily feel the same.

And the more I thought about it, the more I realized that my favorite parts of The Love Hypothesis weren’t necessarily the huge moments anyway.

They were the little things.

The pumpkin “sludge.”

The teasing.

The inside jokes.

Adam remembering things about Olive.

The moments when he quietly takes care of her.

Olive slowly feeling safe enough to trust him.

Those were the moments that made me believe in their relationship.

Yes, I loved the fake dating.

Yes, I loved the sexual tension.

And YES, I loved the spice.

But those things worked because the emotional foundation underneath them was already there.

The movie gave me pieces of that foundation.

The book gave me the whole thing.

The Love Hypothesis Book vs. Movie: The Book Wins for Me

I’m still glad I watched the movie. There’s something fun about seeing characters you just spent an entire novel imagining suddenly brought to life on screen. And I know a book adaptation can work for me because I gave both The Deal and its Prime Video adaptation, Off Campus, five stars. Unfortunately, The Love Hypothesis didn’t give me that same experience. And there were definitely moments when I enjoyed seeing scenes I recognized from the book.

But the movie didn’t recreate the feeling I had while reading The Love Hypothesis.

Maybe the story simply needed more time. Maybe a limited series would have allowed Olive and Adam’s relationship more room to breathe. Or maybe the movie needed to be more selective about what it condensed.

Because this romance depends on accumulation.

One little interaction.

Then another.

And another.

Until suddenly the fake relationship doesn’t feel very fake anymore.

The movie gave me the major beats of Olive and Adam’s story.

The book gave me all the moments between those beats.

And apparently, those were the moments I loved most.

So, if you’ve only watched The Love Hypothesis movie and you’re wondering whether the book is still worth reading?

I think there’s so much more of Olive and Adam waiting for you on the page.

And if this book taught me anything about my own reading taste, it’s that I apparently have a very specific weakness:

Give me fake dating, a little grumpy/sunshine, plenty of banter, emotional vulnerability, a man who pays attention and takes care of the woman he loves, and enough spice to make all that tension worth it.

Yeah.

I’m going to need more Ali Hazelwood. 🌶️💕

What’s Next for Tawni’s Book Nook?

Next up, I’m reading Thirty, Flirty, and Forever Alone by Christina Ricci.

I’m still early in the book, so I don’t have much to say just yet. But once I finish, I’ll be back to share whether this one earns a spot among my favorite romance reads or leaves me wanting something more.

Until then, happy reading! 📚💕
