Demon by Tory Richards

Demon - He's a known womanizer and a man with secrets, but he runs Desert Rebels with an iron fist. He had an old lady once, and he doesn't want another one. A spirited little club girl catches his eye, but fear of commitment forces him to push her away. Trouble and betrayal in the MC brings them back together, leaving him with a decision to make--either trust her and claim her, or send her away for good.
