As heir to HemoCorp Industries, vampire Sophronia Vega has devoted herself to the company her family founded. Most recently, she's led the creation of Stokr: the wildly successful dating app that pairs lusty vampires with humans they can't accidentally, er, eat. But when Stokr's matching technology goes haywire-and vampires start draining their dates-Sophronia's disciplined life goes up in flames. Enter Casey Amato, the human software engineer whose team programmed Stokr. Casey knows the Stokr failure wasn t a glitch-the app's been sabotaged. To fix it, he'll have to convince the gorgeous, guarded vampire exec that someone in her inner circle has betrayed her. Sophronia has never met a human who makes her feel quite so . . . thirsty. But to fix her app and save its users, she must team up with the brilliant programmer. As they hunt the traitor, their attraction burns hotter, and the stakes couldn t be higher. Because without Stokr, giving in to temptation could be deadly.
