Maya Banks the Enforcers Series: Books 1-3: Mastered, Dominated, Kept

MASTERED:
She stood out in his club like a gem, beautiful and fresh. Drawn to her innocence, he summoned her to his private quarters. He sensed her fear. He also recognized the desire in her eyes. And he knew he must possess her. The moment he told her what he wanted, she couldn't resist. Instinct told her to run, but her heart said to stay and walk the fine line between pleasure and pain. Though she wasn't sure she could ever completely surrender, the primal part of her wanted to try, even knowing that this man could break her in ways she'd never imagined. Because once he'd possessed her, he would own her and it'd be too late to turn back.

DOMINATED:
In Drake's shadowy world, his enemies would exploit any weakness to bring him to his knees. So he never allowed himself to care about anyone and became a force to be reckoned with. That is...until Evangeline--his angel--managed to slip past his defenses. She was his to protect. And to protect her, he had to do the unthinkable and drive away the only good thing in his world. But he will stop at nothing to get her back. Devastated and destroyed, Evangeline doesn't know what made Drake turn on her in such a shocking manner. When Drake finds her again, Evangeline realizes there is more to his world than she ever imagined. She must decide if she can again trust--and submit--to the man who holds her wounded heart in his hands.
