Michael Mulcahy, successor to a long line of NYC cops, has learned enough from his brothers' mistakes to know that Libby Crowne Vandermark, a fellow FBI agent and former debutante from the Upper East Side, is all wrong for him. He just needs to slake his relentless lust for her. This undercover operation, where they pose as a married couple at a "second honeymoon" spa, is the perfect excuse to do it.

Libby can't believe she's stuck with Neanderthal Mulcahy. Having grown up with three chauvinist brothers and a dominant father, she goes out of her way to avoid men like him. If she can just keep her eyes off him while they're together, every day and night, she'll get through this.

Until they realize just how perfectly incompatible they are.
