Lucy is a socially awkward genius who must learn about passion to avoid losing her grant. Jensen is her neighbor and the one person she finds remotely appealing. When Lucy and Jensen start making chemistry of their own, she must decide what's more important, analyzing her passions or giving into them?Lucy London puts the word genius to shame. Having obtained her PhD in microbiology by the age of twenty, she's amassed a wealth of knowledge, but one subject still eludes her—people. The pendulum of passions experienced by those around her both confuses and intrigues her, so when she’s offered a grant to study emotion as a pathogen, she jumps on the opportunity. When her attempts to come up with an actual experiment quickly drop from lackluster to nonexistent, she’s given a choice: figure out how to conduct a groundbreaking study on passion, or lose both the grant and her position at the university. Put on leave until she can crack the perfect proposal, she finds there’s only one way she can study emotions: by experiencing them herself. Enter Jensen Walker, Lucy's neighbor and the one person on the planet she finds strangely and maddeningly appealing. Jensen's life is the stuff of campus legend, messy, emotional, complicated—in short, the perfect starting point for Lucy's study. When her tenaciousness wears him down and he consents to help her, sparks fly. To her surprise, Lucy finds herself battling with her own emotions, as foreign as they are intense. With the clock ticking on her deadline, Lucy must decide what's more important: analyzing her passions...or giving in to them?
