Summoned to study at The Academy of Avalon, sixteen-year-old Laurel learns about the town with friend Tamani, while honing her long-forgotten skills as a Fall faerie in order to protect her human family and Avalon from trolls.

As her senior year of high school starts, Laurel is just beginning to adjust to Tamani's absence when he suddenly reappears, telling her he must guard her against the returning threat of the trolls that pose a danger both to her and to Avalon.
