Nutcracker

The 11th standalone novel in the Claus Universe.
Once upon a time, there was a toy store filled with magical playthings and fantastical stories. But not anymore. That was a long time ago.
When Marie arrived, the place was cobwebs and empty shelves. Little dry pellets covered the floor. Aunt Rinks called them dirt balls. They weren't dirt balls.
The place didn't feel like Christmas. Nothing did anymore. What Marie wanted, she couldn't possibly have. A leaky air mattress and a self-absorbed aunt was all she got. But Christmas wasn't about what you wanted; it was about what you needed. Godfather told her that. That was when he told her the tale of the nutcracker.
"You must find the princess," he told Marie. "She's been waiting for you."
It was a story, nothing more. Marie didn't believe in fairy tales or Christmas spirit anymore. Certainly didn't believe in a wooden soldier and a cursed princess who needed saving. Until she discovered the gift.
Marie and her brother, Fritz, find a small box hidden in the old toy store. When they open it, the real journey begins. Marie discovers the nutcracker is more than just a silly toy. The princess isn't a metaphor. The nutcracker shows Marie a truth hidden inside her.
They'll have to hurry to save the princess. When Aunt Rinks finds the gift, she aims to take everything they've discovered for herself, to leave Marie and Fritz with nothing and the princess still cursed. The journey, however, isn't a game. It will reveal Marie's true nature.
What happens next is not what anyone wanted for Christmas.
