Demon King (Claimed By Lucifer Book 1)

When my best friend goes missing in Las Vegas, there’s only one man I can turn to for help. Lucas Ifer. Billionaire playboy. King of Sin City. And…the devil himself? He agrees to help me, but in exchange he wants one thing: me. 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.
