Christmas is Carla's favorite holiday of the year. She goes to her grandparents' house and eats grandma's special recipe--a perfectly delicious cornbread. She listens to her grandpa Doc's marvelous stories about traveling the world. And, best of all, she spends lots of time with her family.

But when Carla accidentally takes a bite out of Santa's sugar cookie, she thinks she's ruined Christmas. How will Santa know to stop at their house if they don't leave him a midnight snack? With her grandmother's help, Carla comes up with a plan, but will it be enough to save Christmas?
