When daydreamer Clementine discovers a mysterious house standing in the middle of town that was never there before, she is pulled towards it by the powerful sense of a mother she never knew. The place is full of snowglobes, swirling with stars and snow and each containing a trapped magician, watched over by Gan, the bitter keeper of the house. One of these is Dylan, a boy who teases her in the real world but who is now desperate for her help.

So Clem ventures into the snowglobes, rescuing Dylan and discovering her own powerful connection to the magic of these thousand worlds. Vowing to release the magicians from the control of their enchantments, Clem unknowingly unleashes a struggle for power that will not only put her family, but the future of magic itself in danger.
