Millie’s a witch, so why can’t she do magic? Despite her mother’s best efforts to teach her, every spell Millie tries goes horribly wrong, but she’s a fabulous cook. When Millie conjures chocolate sauce instead of a transformation potion, her mother gives up and sends her to the Enchanted Forest School, where she’s bullied by goblins, snubbed by an elf, and has her hat stolen. Even as Millie’s magical talent begins to develop, turning her house ghost into a frog and accidentally charming her entire class, Millie starts to wonder: what if she’s not a witch at all? To find out, she and her new friends embark on a dangerous quest to find Millie’s father in the Logical Realm, in contemporary Salem, MA.

Deep in a fantasy realm adjacent to our own, the Enchanted Forest School is located in the branches of an enormous oak tree and has a dragon for a headmistress. Millie’s initial delight in attending school rapidly fades as she struggles in the unfamiliar social environment, encountering fellow students of magical races, making new friends, and discovering that her mother’s style of magic isn’t the only one available.
