For helping Lord Valentine regain his throne, the young street urchin Hissune is sent into the depths of the Labyrinth, a massive library of memory cubes in which the entire history of Majipoor is preserved. While he waits for a summons to return to Castle Mount, he relives the lives of Majipoor's most notorious inhabitants, learning more about the people and his new land than anyone else in the kingdom. As he becomes one with its many peoples--dukes and generals, thieves and murderers, Ghayrogs and Metamorphs--he discovers wonder, terror, longing, love, and wisdom that will shape his destiny.
