Sixteen-year-old Lexie Barlow has spent most of her life convinced that Harry Potter saved her from the ordinary. As a Muggle from London with no magic to her name, she knows Hogwarts only through dog-eared paperbacks, late-night movie marathons, and an encyclopedic knowledge of spells she’ll never cast. Shes taken all the online quizzes, slytherin every time. Shes knows the lore and the classes. She knows the fate of the school. Magic, as far as she knows, is fiction—comforting, impossible fiction.
