‘Contemporary romance’s unicorn: the elusive marriage of deeply brainy and delightfully escapist.’ Christina Lauren, New York Times bestselling author of The Unhoneymooners

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 on her way to a happily ever after was always going to be tough, scientists require proof. So, like any self-respecting woman, 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 he agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire and Adam surprises her again with his unyielding support (and his unyielding abs), their little experiment feels dangerously close to combustion.

Olive soon discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.

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.

This tackles one of my favorite tropes - Grumpy meets Sunshine - in a fun and utterly endearing way... I loved the nods towards fandom and romance novels, and I couldn't put it down. Highly recommended!
