The daughter of rich but neglectful parents, Terisa Morgan lives alone in a New York City apartment, a young woman who has grown to doubt her own existence. Surrounded by the flat reassurance of mirrors, she leads an unfulfilled life - until the night a strange man named Geraden comes crashing through one of her mirrors, on a quest to find a champion to save his kingdom of Mordant from a pervasive evil that threatens the land.
Aided by the powerful magic of Vagel, the evil Arch-Imager, the merciless armies are marching against the kingdom of Mordant. In its hour of greatest need, two unlikely champions emerge. One is Geraden, whose inability to master the simplest skills of Imagery has made him a laughingstock. The other is Terisa Morgan, transferred to Mordant from a Manhattan apartment by Geraden’s faulty magic. Together, Geraden and Terisa discover undreamed-of talents within themselves—talents that make them more than a match for any Imager... including Vagel himself. Unfortunately, those talents also mark them for death.
