The gripping conclusion to the acclaimed Arthurian fantasy trilogy from #1 New York Times bestselling author Kiersten White finds Guinevere questioning everything—friends and enemies, good and evil, and, most of all, herself. While journeying north toward the Dark Queen, Guinevere falls into the hands of her enemies. Behind her are Lancelot, trapped on the other side of the magical barrier they created to protect Camelot, and Arthur, who has been led away from his kingdom, chasing after false promises. But the greatest danger isn’t what lies ahead of Guinevere—it’s what’s been buried inside her. Vowing to unravel the truth of her past with or without Merlin’s help, Guinevere joins forces with the sorceress Morgana and her son, Mordred—and faces the confusing, forbidden feelings she still harbors for him. When Guinevere makes an agonizing discovery about who she is and how she came to be, she finds herself with an impossible choice: fix a terrible crime, or help prevent war. Guinevere is determined to set things right, whatever the cost. To defeat a rising evil. To remake a kingdom. To undo the mistakes of the past...even if it means destroying herself. Guinevere has been a changeling, a witch, a queen—but what does it mean to be just a girl?

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.

With the Archipelago of Dreams in the hands of the Echthroi and the link to the Summer Country lost, the Grail child, Rose Dyson, the new Cartographer, Edmund McGee, and the Caretakers Emeritus seek to rebuild the Keep of Time but face a terrible new enemy who was once an ally. Illustrations.

The exhilarating final book in the Otherworld Chronicles trilogy, which School Library Journal called "a surefire hit with the legions of Rick Riordan fans." Artie Kingfisher, his sister, Kay, and the New Knights of the Round Table have finally reached the legendary isle of Avalon. But before Artie can take his place as King Arthur reborn, he must recover nothing less than the mythical Holy Grail. And as the greatest battle of his life looms, Artie finds himself facing off against the one person he never dreamed he'd be fighting. In The Dragon King, Artie's life-changing quest comes to a spectacular close as the young king discovers what it truly means to be a hero. Rich in mythology and bursting with twenty-first-century fun, this high-spirited spin on Arthurian legend is perfect for middle grade fans of Percy Jackson, the Alex Rider Chronicles, and House of Secrets.

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.
