Publisher's Summary

Now see Adam pine for Olive in a special bonus chapter!  

The Instant New York Times Best Seller and TikTok Sensation!

As seen on The View!

A BuzzFeed Best Summer Read of 2021

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 PhD 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.

Critic Reviews

An Indie Next Pick!

"A literary breakthrough…The Love Hypothesis is a self-assured debut, and we hypothesize it's just the first bit of greatness we'll see from an author who somehow has the audacity to be both an academic powerhouse and divinely talented novelist."—Entertainment Weekly

“Contemporary romance's unicorn: the elusive marriage of deeply brainy and delightfully escapist...The Love Hypothesis has wild commercial appeal but the quieter secret is that there is a specific audience, made up of all of the Olives in the world, who have deeply, ardently waited for this exact book.”—Christina Lauren, New York Times bestselling author 

“Funny, sexy and smart, Ali Hazelwood did a terrific job with The Love Hypothesis.”—Mariana Zapata, New York Times bestselling author 

Editor's Pick

The scientific method meets romance (with a side of fake dating
Are you looking for a fun, feel-good story that you won’t be able to hit pause on? You just found it. If I didn’t have to sleep, I easily could have listened to The Love Hypothesis in one sitting. Featuring a third-year PhD candidate, a broody professor with a heart of gold, and their fake relationship, this is one of the best romances of the year. Everything about Olive’s and Adam’s lives feels so warm, friendly, and real—all while shining a light on the difficulties of being a woman in the hypermasculine world of STEM. Oh, and did I mention that author Ali Hazelwood is also a professor with a PhD in neuroscience? There’s truly nothing about this listen to dislike. Do yourself a favor and pick it up ASAP, because I think everyone is going to be gushing over this one. —Michael C., Audible Editor

Funny. Snarky. Intelligent. Real.

I devoured the book in one day (in-between family gatherings and kids). I couldn't put it down.

Then a few days later I inhaled the audiobook. GOD I adore Callie Dalton. Hands down my favorite female narrator (not an intentional nod to Mariana Zapata but I'll leave it there to honor the slow burn queen 😂)

Olive is the best kind of mess. She's frazzled from her PhD. She's grieving the loss of her mother to pancreatic cancer (which is fueling her research into easier/cheaper screening methods). She adores her friends and will do anything for them... which is how she ends up kissing Dr Adam Carlson.

Adam is the resident grump/beast - instilling fear into graduate students (but all in the name of scientific excellence, of course). He agrees to a mutually beneficial fake dating relationship with Olive after the whole kissing-incident.

Both Olive and Adam are navigating the challenges and obstacles of academia in their own unique ways - research, funding deficits, grants... i.e. lots of work, questionable returns. But science! Meanwhile juggling their fake-relationship and not at all (!!!) catching feelings.

Cancer is a near and dear topic to me (my mum died of cancer and i am currently fighting cancer) so I was gut punched during several scenes that this was discussed.

The banter and incredible one-liners in this story are perfection. Funny. Snarky. Intelligent. Real.

The relationship between each character and their individual friends is beautiful. The development of their relationship together feels *just so good*.

Read if: you're traumatized from academia and/or a STEM nerd, if you love Mariana Zapata & Helen Hoang, if you love sharp and funny banter, if you like a delicious slow burn with a fun twist on some classic tropes, if you're wild for sunshine/grumpy books.

I'm so so excited to see this book climb the bestseller list. I know its going to be (frankly it already is) a total hit.

Overall score: 5++ (this is my new bible. I will study it religiously)
Smut score: 3.5/5 (slow burn, explicit but not super kinky other than *one* thing that had me going "ohhhh" 🥵🌶)

frustrating

I was looking for a light funny romance because I love a good love story and sometimes I just don't have the energy for anything heavy. This book was so frustrating because the storyline follows what happens after the F MC tells lie after lie, after lie, after lie, after lie! She was just so weak that she could never reveal the truth to the M main character. The author is smart so why give us a whimpering, indecisive lead F? There was an HEA, which I always need, but it took so long to get there, and it wasn't fulfilling.
Side note, I love this narrator and the side characters were hilarious.
Would I recommend this book? Not if I want my friends to value my book opinions.

Such a frustrating plot

I wish I could enjoy this book but honestly I just felt frustrated with the characters the entire time. It had incredibly adorable scenes but the entire conflict is just miscommunication/lack of communication so I it gets to the point where you just want the book to end.

So cute and frustrating at the same time..

There is so much to love about this book. It’s a very cute story and most of the characters are great. The dialogue and witty banter is fun to read. Then… somewhere in the middle of the story, you start to get super frustrated that the lead is so naïve and wimpy. The lead character gets neon signs thrown in front of her face over and over and then somehow works up a mental story to ignore everything. It’s not very believable and gets annoying after awhile. I got to the point where I just wanted it to be over. I liked the story enough that I wanted to finish the book but was ready for the hea.

Absolutely perfect.

Please tell me she has more books… Its like the Frasier of romance novels. You don’t understand the highbrow joke but you know it’s supposed to be funny.

What on Earth was this?

Thank God I grew up in the age of Nicholas Sparks writing romance novels, because good grief these new romances are weak. I blame 50 Shades of Grey and Twilight for this narrative of wimpy weak women getting the attention of genius, headstrong, independent, powerful men. Olive is 26 years old and doesn't have the faintest idea about love. Did she live in a shell her entire life? She watches rom-coms with her roommates on the weekends and you mean to tell me she can't recognize when a guy has a thing for her? My problem with Olive is that she plays the victim too much. She thinks she's underserving of love, attention and even friendship. I hate when she complains that everyone around her either dies or leaves; the "everything I touch gets destroyed." And as for Adam, he really couldn't find anyone else? I'm certain Academia pumps out some brilliant and sensible wifey material. Beyond that, the story had potential but please let go of the smart guy preys on dumb girl storyline. It gives the rest of us a bad name.

A new favorite author!

I adore this book and am pleased to find a new author for my favorites list. Ali Hazelwood's insights into romance while ensconced in academia are so spot on, I absolutely loved it! Callie Dalton is an excellent narrator, which is such a wonderful pairing for this author. A+

Delightful!

My short and sweet review: Every aspect of The Love Hypothesis is wonderful — the characters, the story, the narration. I only wish I could listen to this book again for the very first time.

Best book I have read in years!

I ordered this book because of tiktok like most people. amazingly it was even better than all of the reviews. it is hands down the best book I have bread and quite some time. There was never a dull spot. I laughed, I antagonized, it just held my attention through the whole book. I would recommend this book to anyone who actually wants to feel amazing about the book you just read.

Neurotic internal monologue ahoy

Thought the heroine would be self assured for a change seeing as though she’s based on Rey but no just a normal romance heroine neurotic with verbal incontinence. I’ll never forgive Bridget Jones for ruining romance heroines

Oh wow.

I loved this book so much. Finished in a day (and a night… it is 5am and I still have not slept). I’ve never smiled and laughed and kicked my legs about madly (out of embarrassment for Olive) whilst reading another book. This is one of those books I wish I could read for the first time again and again.

I went into this with high book standards. I had just finished the hating game, me before you, and series of other 5 star reads - so for me to love this book so much after that cloud nine book marathon should say something.

At first, I definitely thought “oh… this would never happen” or .. “this is too Typical a cringe rom com trope”. But the characters were so aware of that, that it became amazing. And by the end, everything was so plot twisty and satisfying that every cringe moment was smoothed out and justified and just made sense.

Read. This. Book.

loved it!

I got so invested in this novel and the stem backdrop is awesome! She leans into the fake relationship trope with wit and the characters are endearing. Very enjoyable light holidays read.
