From the New York Times bestselling author of The Love Hypothesis comes a smart, sexy STEMinist rom-com. Bee Koenigswasser lives by one rule: What would Marie Curie do? So when NASA offers her the lead on a dream neuroengineering project, the answer is obvious—yes. The problem? She has to co-lead with Levi Ward, her graduate-school nemesis. Tall, dark, brilliant—and the last person Bee wants to work with. As her equipment vanishes and colleagues dismiss her, Levi unexpectedly starts backing her ideas and standing by her side, and the line between enemy and ally blurs fast. Sparks fly, neurons fire, and Bee must decide whether to risk her heart. Witty, nerdy, and irresistibly romantic, Ali Hazelwood proves once again that science is sexy and love can come from the most unlikely places.
