Olive Smith may have just made a huge mistake. 

All she was trying to do was convince her best friend and fellow Ph.D. candidate, Anh, that she was really and truly over her ex-boyfriend. Unfortunately for Olive, her way of proving that fact was panic-kissing the biggest asshole in their department - Professor Adam Carlsen. 

For reasons mysterious to Olive, Adam seems amused by her predicament and agrees to be her fake boyfriend to keep the charade up for Anh. But as the weeks of pretending drag on, it seems more and more obvious that Olive and Adam really have something. A cruel colleague and a disastrous run-in at a scientific conference threaten to derail everything for Adam and Olive unless Olive has the courage to speak up for herself. I loved reading a fun romance set in the STEM field!

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.

About the Author

Ali Hazelwood is the #1 New York Times bestselling author of Love, Theoretically and The Love Hypothesis, as well as a writer 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 US to pursue a PhD in neuroscience. When Ali is not at work, she can be found running, eating cake pops, or watching sci-fi movies with her three feline overlords (and her slightly-less-feline husband).
