At Her Pleasure by Joey W. Hill

It was a night for doing stupid things…

Ten years ago, Mick should have arrested the drunk, angry woman vandalizing a cemetery. Instead, on that cold night, he yielded to her pain and rage, and let her go. Now a former cop, he’s come to New Orleans on business, which brings him face to face with the woman he never forgot.
Cynbad Marigold is a successful businesswoman and a formidable Domme, a Mistress who chooses subs who need enough pain to appease her limitless craving to inflict it. Most subs safeword before she goes too deep, but when Mick reappears in her life, he doesn’t want safety. In uncovering the shocking depths of his own darkness, Cyn realizes how much she wants to give him the home he needs…safe in the shadows of her soul.
Whose darkness will take them deeper—and will their bond keep them from going too far?
