Millie hates Christmas. Despises everything about the holiday. Her ghost of Christmas past still haunts her. But this year, she promised her little sister she’d spend the holidays with her. And unlike her father, she’ll never break a promise.

When they decide to take a family trip to the mall to get their picture taken with Santa Claus, she has no idea what’s in store for her.

It was just supposed to be a silly little wish made to a man who was dressed in a costume. A man hired by the people who manage the shopping center. It wasn’t supposed to come true. But when Millie finds the naughty thing she wished for tucked under her pillow, her world is turned upside down.

This Christmas, she’s about to discover that Santa Claus is real, magic does exist, and Elves may be more naughty than nice.
