It's A Wonderfully Sexy Life by Hope Tarr

Baltimore street cop Mandy Delinski isn't expecting any miracles this Christmas. She's thirty, a little too round, still very single and she lives with her parents. So who could have guessed that her whole life would change before New Year's Eve? That a simple job policing a Christmas party would find her in the arms of sexy-as-sin bartender Josh Thornton? That they would be on the brink of making love before the night ended? That Mandy would find her perfect man in the morgue the next day? Or that she'd be given a magical chance to go back a week, save Josh…and have the best sex of her life. Does Christmas get any better than this?
