Three years ago, Brynn Dalton made a rare error in judgment and had a one-night stand with the one man she swore would never get into her designer panties. Will Thatcher was exactly the type of sexy playboy that good girls like Brynn stayed away from and when Will moved across the country just days after their fling, Brynn vowed to put him behind her, even as the memories haunt her.

Now Will Thatcher is back and just in time to see Brynn's perfectly structured life begin to crumble. Her job is dull, her social life is tedious and Brynn's perfect cardiologist boyfriend doesn't seem to be in any hurry to get to Tiffany & Co. More than ever, Brynn needs her childhood nemesis to keep his distance.

But Will isn't content to be Brynn's dirty little secret any longer. This time, he's out to show Brynn Dalton that the imperfect man might just be the best mistake of her life.
