When a museum executive secretary, who barely tolerates men, has a run in with an infamous BDSM Master, Neil Cannon, a man who lives to discipline women, there's little she can do about it. Why?

The Master thinks Charlotte, a.k.a Charlie, is her kink-loving, totally outrageous, and continually stirring-up-trouble twin sister. And after what Charlie just did, he has to keep thinking that. At least until she can find a way to climb out of the huge mess her well-meaning intentions have landed her in. She'll take the punishments the Master intends for her twin. She'll even put up with him and his misogynistic antics if it means she'll be able to unlock the secrets that will save her family. All she has to do is behave like her sister. How hard could it be to emulate a fearless, over-confident, rebellious woman, with highly questionable sexual standards?

Neil's been waiting months for the chance to deal with this audacious sub who's been jacking up the testosterone levels of his vanilla crew whenever her sports car needed maintenance. That's why he made the service call himself. He's confident she won't be yanking his chain, because if she tries he's prepared to yank it right back.

Or so he thought until she turns out to be different than what he expected her to be. She starts pushing buttons he didn't know he had. She's flipping internal switches, lighting things up, creating a whole new level of dominant need he's determined to explore, enjoy, and satisfy.

Unfortunately, before either of them can get a handle on the D/s chemistry exploding between them, she takes off. It's then he discovers that she's invited a part of his past, that he's promised to steer clear of, right to his front door.
