Frannie Cavanaugh is a good Catholic girl with a bit of a wicked streak. She has spent years keeping everyone at a distance - even her closest friends - and it seems like her senior year is going to be more of the same...until Luc Cain enrolls in her class. No one knows where he came from, but Frannie can't seem to stay away from him. What she doesn't know is that Luc is on a mission. He's been sent from Hell itself to claim Frannie's soul. It should be easy - all he has to do is get her to sin, and Luc is as tempting as they come. Frannie doesn't stand a chance. But he has to work fast, because if the infernals are after her, the celestials can't be far behind. And sure enough, it's not long before the angel Gabriel shows up, willing to do anything to keep Luc from getting what he came for. But if Luc fails, there will be Hell to pay...for all of them.
