An icy vampire corporate heiress and a human software engineer must team up to thwart the saboteur who's turned their sexy human-vampire dating app into a bloodbath, in this mystery romance romp by USA Today bestselling author Alexandra Vasti.

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.
