The Shadow King uses the Spear of Destiny to enlist an unstoppable army of Dragon shadows. And after the Archipelago falls, the Shadow King intends to use the turmoil of World War II to take over both worlds.
All the legendary Caretakers, past and present, come together to save two worlds, 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 clockwork companion, the owl Archie; a dead professor of ancient literature; and the mythical knight Don Quixote.
