Seven years after the events of The Shadow Dragons, John, Jack and Charles are finally able to return to their beloved Archipedlago 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 and attempt to restore Time. They must journey through a forgotten door from the destroyed Keep of Time in order to seek out the Dragon's 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.

The dragons may be out of the bag, but Jaxon is ready to hatch some magic of his own in this third book in the critically acclaimed series. Ever since the baby dragons were returned to the magical realm, things have been off. The New York summer has been unusually cold. A strange sleeping sickness is spreading across the city. And Jaxon’s friends Kenny and Kavita have begun to change, becoming more like the fairy and dragon they once cared for. On top of all that, Jax is hiding a secret—Vik entrusted him with a phoenix egg! Jax wants to help his friends and learn how to hatch the phoenix, but so far his lessons as a witch’s apprentice haven’t seemed very useful. Where can he find the strength—and the magic—he needs?

The Caretakers of the Imaginarium Geographica are at war. The Imperial Cartological Society, led by Richard Burton, have collected all of the doors from the Keep of Time, and are building a new tower in our world at the request of an old enemy: The Winter King’s Shadow. He has a terrible weapon – The Spear of Destiny – that can be used to command the shadows of anyone it touches…including the protectors of the Archipelago, the dragons. With a ship called The Iron Dragon, the Shadow King regains passage to the Archipelago where he uses the power of the Spear and the portals of Time to enlist an unstoppable army of Dragon Shadows. And after the Archipelago falls, he intends to betray the Allies in our world – but not to align himself with the opposition. The Shadow King intends to use the turmoil of WWII to take over BOTH worlds. All the legendary Caretakers, past and present, come together on a great island in the northermost part of the Archipelago to decide the ultimate fate of the Imaginarium Geographica, as a terrible battle ravages the lands around them. And their only hope lies with a small group of companions who are on the quest for the broken sword Caliburn: the Grail Child Rose Dyson; her mechanical companion, the owl Archie; a mouse with an attitude; a dead Professor of Ancient Literature; and the mythical knight, Don Quixote. They must sail beyond the ends of the Archipelago in search of the sword, and the only being alive who can repair it: a scholar, who, once upon a time, was called Madoc.
