All Clara wants is a key – a special key that will unlock a box that holds a valuable gift from her late mother. When she is presented a golden thread at her godfather’s annual holiday party it leads her to the coveted key, which promptly disappears into a strange and mysterious parallel world. It’s there that Clara meets a solider named Philip, a gang of mice and the regents who rule over three realms: Land of Snowflakes, Land of Flowers and Land of Sweets.
