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.
