The Love Hypothesis by Laura Steven

Physics genius Caro Kerber-Murphy knows she’s smart. With straight As and a college scholarship already in the bag, she’s meeting her two dads’ colossal expectations and then some. But there’s one test she’s never quite been able to ace: love. And when, in a particularly desperate moment, Caro discovers a (definitely questionable) scientific breakthrough that promises to make you irresistible to everyone around you, she wonders if this could be the key. What happens next will change everything Caro thought she knew chemistry – in the lab and in love.

Is her long-time crush Haruki with her of his own free will? Are her feelings for her best girl friend some sort of side-effect? Will her dog, Sirius, ever stop humping her leg?
