Becca Gibbs is the Vice President of Vic`s Pretzels by day and Satan`s right-hand woman by night. True, Satan isn`t all fire and brimstone. He`s a lothario with a taste for women, fine things and soul harvesting. But still, the devil`s the devil, and he loves making Becca`s life hell. She`s desperate to cut the cord between her and Satan, but Becca Gibbs is a Rivka, a being created by Satan and supported by Satan`s life force. If she quits, she dies. Enter Nick Rawlings. Nick is a gun-for-hire, a man who doesn`t shy away from a fight. Nick`s sister has been kidnapped, and the only thing he has to go on to get her back is a cryptic message saying that unless he kills Satan, she`ll die. When Becca and Nick realize they have a common cause, the sparks start flying. But they`ll need more than chemistry to defeat the King of the Underworld.
