Amelia is an author crashing on her sister's couch in King's Fall. One fateful day, on the way back from a well earned break, she notices goons following her and her sister. As a struggling thriller/mystery author, she knows how this ends. So, naturally, they book it... only to run into Knox, the black market Devil of King's Fall. Knox runs the casino that Penny's, her sister, shitty husband looses all his money at, and Knox is ready for them to pay up.

Amelia demands she be taken in her sister's place. Knox doesn't deal in people, especially with the blue haired vixen threatening him with a rusty knife. But he likes her spunk, and so he strikes a deal: Twenty-four hours, she belongs to him. If she's a good girl and keeps her word, Penny's slate is wiped clean.

It was meant to be one torrid night of passion and she'd never see him again. A deal's a deal. But there are more villains in King's Fall than she knows. An old enemy of Knox's is after his head, making the woman he secretly pines for a target... and so Amelia might have to make a few deals with the devil to survive.
