One Christmas Eve night, Clara enters the Four Realms. There she watches a ballet that tells her the story of how this mysterious world of sweets, snowflakes, flowers, and amusements came to be. Clara learns the Fourth Realm is unstable, home to the tyrant Mother Ginger. But when Clara goes on a mission to save the day, she finds that while the story was beautiful, it may not have been entirely true. It will be up to her to change the dancer's tale of the Realms... and find a happy ending.
