Mia is an awkward 12-year-old who recently arrived at a new boarding school, where she is given a book and bracelet that are more than they appear to be on the surface. The powerful items can transport Mia to a magical storybook world, Centopia, where she becomes a flying elf who can talk to unicorns. In Centopia, Mia must save the land’s unicorns from an evil queen. Her new friends join the mission, elven warriors Mo—the son of elven King Raynor—and Yuko, who has been chosen as a protector of the unicorns.
