The Love Hypothesis

The Instant New York Times Bestseller 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 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.

Going into this book, I didn’t expect to relate to Olive so deeply. Like Olive, I don’t crush easily. I have to get to know someone well before developing feelings for them. At 22-years-old, I’ve gotten used to my own (or rather lack of) romantic experiences not being presented in pop culture or mainstream media. I’ve never seen myself in a romance novel until now, and I cannot thank Hazelwood enough for that.

THE LOVE HYPOTHESIS takes classic romance tropes and flips them on their side. By putting a character who doesn’t have a sexual side at the forefront of her novel, Hazelwood creates a refreshing and inclusive story that’s a snapshot of real life.

The first book I've read of hers, it got me hooked! And all of the cameos in some of the other books that she has written from Olive and Adam is just sooo mwah

It was a well writen book. Started off slow at first but was really easy to comprehend and imagine.

A truly fun rom-com read. This book is the junk food of books. So though enjoyable, there is nothing profound in this book. It would make a great palate cleanser after a heavy book.

I highly enjoyed the drops of science interspersed throughout this book, loved the chemistry, and the story. Great easy reading and delightful rom-com.
