From the New York Times bestselling author of The Love Hypothesis comes a new STEMinist rom-com in which a scientist is forced to work on a project with her nemesis - with explosive results.

Bee Königswasser lives by a simple code: What would Marie Curie do? If NASA offered her the lead on a neuroengineering project - a literal dream come true - Marie would accept without hesitation. Duh. But the mother of modern physics never had to co-lead with Levi Ward.

Sure, Levi is attractive in a tall, dark, and piercing-eyes kind of way. But Levi made his feelings toward Bee very clear in grad school - archenemies work best employed in their own galaxies far, far away.

But when her equipment starts to go missing and the staff ignore her, Bee could swear she sees Levi softening into an ally, backing her plays, seconding her ideas... devouring her with those eyes. The possibilities have all her neurons firing.

But when it comes time to actually make a move and put her heart on the line, there's only one question that matters: What will Bee Königswasser do?

Ali Hazelwood is the New York Times bestselling author of 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).
