Demon King by Elizabeth Briggs
I made a deal with the devil. Now he’s claimed me as his 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 owns my soul for all eternity. 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, perfect for fans of Laura Thalassa, Amelia Hutchins, Jennifer L. Armentrout, and Sarah J. Maas.
