Strange wickedness is rising up on the magical isle of Fincayra. To save his homeland, and his destiny, Merlin is forced to travel to frightening places—both on the land and within himself. Joined by Hallia, the deer-woman he has grown to love, and by his own mischievous shadow, Merlin discovers a magical mirror that can alter anyone's fate. But when he looks into it, the person he sees is the person he least expects to find.

For the past two years, Bailey Morgan has lived a double life: high school student by day, ancient mystical being by night. As the third Fate, Bailey literally controls the fate of the world, but as Plain Old Bailey, her life is falling apart. She’s got a tattoo that was supposed to be temporary (but isn’t), friendships that were supposed to last forever (but might not), and no idea what her future holds after high school graduation. Then Bailey meets the rest of the Sidhe, an ancient race defined by their power, beauty, and a sinister habit of getting what they want at any cost. Before Bailey knows it, she’s being drawn into an otherworldly web more complicated than anything she weaves as a mortal Fate.
