Christmas is both naughty and nice this year when a single dad and his best friend's sister celebrate with some secret (steamy) romance and festive fun, perfect for fans of Maggie Knox and Lyssa Kay Adams.

Charlotte Calhoun has avoided Hayden Porter, her older brother's sexy-as-sin best friend, ever since that mortifying night when he flat-out rejected her. Fine. Except this Christmas season, they're thrown together at a snowy ski resort for her brother's bachelor party, complete with mistletoe, cozy fireplaces, and adjoining rooms. She can tell herself to get over Hayden, but holiday cheer is turning to holiday lust every time he is within ten feet of her.

Between being a full-time single father and his high-pressure college coaching job, a romantic relationship is off the table for Hayden. But he's fought his attraction to Charlotte for as long as he can. A one-night stand is starting to sound like a good idea-as long as her brother never finds out. But with two long weeks until the wedding, hiding their growing feelings is going to take a Christmas miracle.
