What happens to Alice when she comes back from Wonderland? Wendy from Neverland? Dorothy from Oz? The three meet here, at Cheshire Crossing -- a boarding school where girls like them learn how to cope with their supernatural experiences and harness their magical world-crossing powers. But the trio -- now teenagers, who've had their fill of meddling authority figures -- aren't content to sit still in a classroom. Soon they're dashing from one universe to the next, leaving havoc in their wake -- and, inadvertently, bringing the Wicked Witch and Hook together in a deadly supervillain love match. To stop them, the girls will have to draw on all of their powers... and marshal a team of unlikely allies from across the magical multiverse.
