Mac Nighthorse, homicide detective, alpha male, and built like an oak, doesn't fit the male submissive stereotype. Nevertheless, that's what he is, though none of his co-workers know it. When he goes undercover at a BDSM club to find a killer, his path crosses with Violet Siemanski, a petite Mistress who can command him with the mere brush of her fingertips across his broad chest. Violet has her own secrets, but as they get closer to who is killing male submissives, she's crystal clear on her top priority. She won't let anyone take Mac from her. Unfortunately, he'll burn the world down to keep her safe - even if he loses his life doing it.
