Alissa is steadily advancing in her magical studies with the last surviving Master at the legendary Hold. But she's haunted by dreams—dreams revealing that other Masters have survived.

Alissa's dreams lead her to a distant island where she and a rescue party discover countless Masters, alive and part of a flourishing magical society. But instead of being welcomed, Alissa finds that she herself may need to be rescued. The Masters' leader, Keribdis, believes that she should be Alissa's teacher, whether Alissa likes it or not. When Alissa rebels, she endangers not only her magic but also her life.
