John, Jack, and Charles (who met nine years ago when they became Caretakers of the Imaginarium Geographica, an atlas of all the lands we think of as imaginary) have come together again. Someone is kidnapping the children of the Archipelago of Dreams - and the legendary Dragonships, which can cross between the two worlds, have disappeared. Their search takes them from Sir James Barrie and Peter Pan, to Jason and the Argonauts, Medea, the Pied Piper of Hamelin, and much more! An inventive, magical adventure that will keep readers riveted.
