In this New York Times best-selling erotic trilogy, a buttoned-up businesswoman takes her friend's advice and has a fling with a stranger on a trip to Vegas - only to find herself under his mysterious, sexy power both in the boardroom and the bedroom.

Kasie Fitzgerald knows who she's supposed to be. She's a rising-star-workaholic at a global consulting firm. She's the fiancée of a well-connected man who's won the approval of her parents. People know that she's reliable, serious, proper, cautious, pragmatic, and yes, a little predictable. She's who Dave and her family want her to be.

But as her 30th birthday looms, buried feelings begin to resurrect. Her friend takes her to Vegas for one last wild-and-crazy night. In a dress much shorter and sexier than anything she has ever dared to wear before, she hits the blackjack tables. And meets him. Under the tailored clothes it's clear that this is a man who is intense, powerful, and maybe even a little dangerous. With a touch of trepidation she accepts his invitation to get a drink, and before long, she's in his hotel room.

She never gets his full name. Perhaps his anonymity is one of the reasons she's able to give herself over to him and to the moment so completely. Perhaps it's why she's just had the most exquisite and passionate sex of her life. Shaken by her own behavior, Kasie tries to chalk it up to one crazy night. But when the mysterious gentleman she's just had a fling with shows up in her office - as the CEO of a firm her company does a billion dollars of business with a year, demanding that she handle his account, and so much more - things will never be the same again. And there's no telling where this will go....
