Michael keeps crying wolf. Now nobody will believe him when he says he saw a pretty girl with red hair steal the Great Book of Neverland. And yet, a pretty redhead, did do it. When Peter Pan and the Darlings finally believe Michael, it's too late, Sienna, the little thief, has already worked out a trade with Captain Hook! He's planning on using it to bring back the meanest monsters that ever roamed Neverland: Loki, Synapse, the Swamp Monster, not to mention the others. The children will have their work cut out for them as they battle them. Maybe they will manage to convince Sienna to stay and help them win their battle.
