Seven years after the events of The Shadow Dragons John Jack & Charles are finally able to return to their beloved Archipelago of Dreams. But even as their return is celebrated by old friends new concerns shadow the reunion namely the threat of Echthroi the primordial Shadow but perhaps even worse the apparent splintering of Time itself. Now the Caretakers must fight against their most fearsome enemy ever & attempt to restore Time. They must journey through a forgotten door from the destroyed Keep of Time in order to seek out the Dragons Apprentice. If they fail it will mean the end of both of the worlds. But success will carry its own price
- a price that may be too high even for the Caretakers to bear.
