Bad girls have all the fun... Trying to fit in with expectations has left Diane Milstrom lonely and dateless for yet another New Year's Eve. After being forced to witness her ex proposing to the woman he dumped her for, she has one too many drinks and makes an uncharacteristically impulsive decision: she's not going to be good anymore. It's gotten her nothing but heartache, and besides, everyone knows bad girls have all the fun. Sam Everly enjoys the lifestyle his family's wealth provides, but he hates the trappings of society that come with it. If he has to attend one more family function full of bored socialites, he just might lose it. Diane Milstrom, his eldest brother's ex-girlfriend, is the worst of the lot...or so he always thought. But when he overhears her making a Bad Girl To-Do list, he starts to wonder if maybe there's more to her than meets the eye. Curiosity gets the better of him, and he volunteers to help her with some of the more...ahem, explicit items on her list. When Sam points out that being naughty with her ex's brother is something only a bad girl would do, Diane can't help but see his point. Besides, she could do worse than a little between-the-sheets action with a sexy guy who makes her heart beat in ways his brother never could. It's only supposed to be a fling, a way to help her stretch her bad girl wings. But the more items they cross off her list, the higher the stakes become. Because if they aren't careful, she just might fall in love...and that's one thing a bad girl should never do.
