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.
