In a time when elves, trolls, little people, and dragons share the earth with humans, alien invaders, convinced that no intelligent life exists on the planet, plan to attack and plunder. Magi in each of the thinking races, forewarned by visions of the Earthdoom, plot to stop the invasion but are unsure of what to do. Following the suggestion of the troll high wizard, 12-year-old apprentice Lithim and his father, Mulng, journey to the oracle Gurda for advice. As the time of the Earthdoom moves closer, the magi work desperately to put a plan into action and save the planet. McGowen's satisfying conclusion to the popular "Age of Magic" trilogy, which began with "The Magical Fellowship" (1991), will delight fantasy fans.
