DEA agent Domino Petracelli is chasing a career-making promotion and nothing will keep her from getting her man. Okay, so she'd rather infiltrate a drug cartel than go undercover as a dominatrix at D.C.'s Xecutive Branch sex club. But she's up to the task. As the leather-clad Mistress Bella, Domino investigates the club's drug ring while juggling a surreal roster of kinky submissives — and resisting one sexy client who's not what he seems.

Police detective Dalton Cutter is a man with a mission — avenging his partner, who was murdered investigating the Xecutive Branch. Retracing his partner's steps, he goes undercover as a club client. Dalton's handled killers, junkies and pimps, but can the Alpha-male cop act submissive long enough to fool Mistress Bella? And will their sexual chemistry, crackling louder than Bella's whip, derail Dalton's investigation?

This romantic suspense pokes a bit of fun at the alphabet soup of D.C. law enforcement agencies, famous for their lack of interdepartmental cooperation. Imagine what could happen if several agencies unknowingly put operatives undercover at the same location—let the sparks fly!
