I made a deal with the devil. Now he claims I'm his fated mate. When my best friend goes missing in Las Vegas, there's only one man I can turn to for help. Lucas Ifer. Billionaire playboy. CEO of Abaddon Inc. King of Sin City. And...the devil himself? Lucas-aka Lucifer-agrees to help me, but in exchange he wants one thing: me. He's dark, dangerous, and wickedly handsome. Oh, and evil incarnate. I should say no, but I can't. I'm that desperate. But when you make a deal with the devil, there's no escaping it. Now he owns my body for seven nights of sin. Even worse, he says I'm his fated mate and that we have a past stretching back through time-but I don't remember any of it. I'm Persephone being claimed by Hades, and I have no choice but to enter his underworld and become his dark queen. Is there any light left in that black heart? Or will his darkness consume me? Demon King is a sinfully sexy Hades and Persephone story with a Lucifer twist. This is book 1 in the Claimed By Lucifer trilogy - a complete series.
