About this audiobook

THE SUNDAY TIMES, NEW YORK TIMES AND TIKTOK SENSATION, AND NOW A PRIME ORIGINAL FILM STARRING LILI REINHART AND TOM BATEMAN! Read it before you see it with Ali Hazelwood's original swoony STEM romance novel - featuring a bonus chapter from Adam's perspective!

A fake relationship between scientists meets the irresistible force of attraction.

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 New York Times and Sunday Times bestselling author of multiple romance novels, 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 crocheting, eating cake pops, or watching sci-fi movies with her three feline overlords (and her slightly-less-feline husband).
