Princess Quinn of Mandria, one of the hidden underground kingdoms that magical beings fled to long ago, has always been curious about Outer Earth, the whole other world on the surface. She has seen many Outer Earth people come and go from the footbridge above the wishing pool in the wizard Melikar's chamber, the only window between the two worlds. She and her childhood playmate, the wizard's apprentice Cam, have long dreamed of a fantastic journey to Outer Earth, but when Cam finds the spell to send them there, things do not go as planned. First of all, only Quinn makes it to the surface. Secondly, and most gravely, she does not know how to return to Mandria.
