The Love Hypothesis (Prime Tie-In) Release Date: September 8, 2026

Published

Ali Hazelwood’s swoony instant New York Times bestselling novel—now in a beautiful movie tie-in edition featuring:

• An all-new foreword from Lili Reinhart
• A cover with exclusive movie art
• Adorable art printed inside the front and back covers
• Both bonus chapters 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.
