A Wild Hunt (Aether Vitalis)

Like most skinshifters, Ariane Conant doesn't have much use for magic, but, as a faerie, she knows it when she sees it. When she's sent to spy on a suspicious group of mages, Ariane uncovers a trio of magic thieves. Recognizing her classmate Kiran Eckhart among the thieves' victims, Ariane rushes to the rescue—and into a race to stop the mages from stealing Kiran's psychic powers forever.
