When Wendy Everly was six years old, her mother was convinced she was a monster and tried to kill her. It isn't until eleven years later that Wendy discovers her mother might have been right. With the help of Finn Holmes, Wendy finds herself in a world she never knew existed--a world that's both beautiful and frightening, and Wendy's not sure she wants to be a part of it.

Duty-bound to marry her friend Tove in order to give the Trylle people their strongest king and queen in history, Wendy, a changeling troll princess, is torn between two other suitors, Finn and Loki.
