Hidden in the back of an old nutcracker and sweets shop is a door...behind it is a magical land full of chocolate rivers, sugar flowers, and candy cane trees.

Christmas used to be the Tannon family's favorite holiday, but thirteen-year-old Oliver can't imagine celebrating after his dad deserted their family. Peace on Earth? Yeah right! Oliver doesn't believe it exists.

His younger sister Nadine is hopeful that this Christmas can still be a happy one now that she has been given a part in the famous Nutcracker ballet.

Fifteen-year-old Felicity will do anything to give her cousins the Merry Christmas they deserve. If only her older brother, Ethan, would get on board with her plans.

Ethan knows the true meaning of Christmas: money, money, money. He's determined to get a job for winter break, but when he wanders into Drosselmeyer's Christmas Emporium, he worries that his new boss has watched Nadine's ballet one too many times.

When masked figures kidnap the eccentric shop owner, the Tannon teenagers follow them through a mysterious back door into a land where fantasy becomes reality. Nutcracker soldiers, the Sugar Plum Fairy, and even Mother Ginger are there to help them on their journey. But where there are heroes, there are also villains. The mice aren't just a part of the fairytale; they're real, and they're tired of losing!

Can these adventurers save the land of sweets and make it back home before Christmas?
