Shadow Master (Shadow Master #1‪)‬

Laen thought it would be a night like most: doing drugs with his friend and, if they were lucky, finding a whore. As an incubus, not much fazes him. But when he realizes the whore they picked up is a warlock -- just the kind of girl who could actually reign him in -- he balks. She doesn't know what she is just yet, and when she finds out, maybe she'll decide she wants him...in some form or another.

Felane had no idea this night would completely change her life. She thought offering her body to two men for a share of their drugs would be a straightforward deal; after all, she'd done it hundreds of times before when she needed a quick fix. But when one of them makes her feel something she's never felt before, something that makes her feel more alive than the drugs ever did, and when she realizes what he is -- and what she is -- she can't get him out of her mind.

Although reluctant to admit it, neither demon nor warlock can stop thinking of the other after their first time together. Their twisted and forbidden relationship grows beyond a single night of cheap sex into something darker and more pleasurable than either ever imagined.
