After a prom-night spell goes badly wrong, witch Sophie Mercer is exiled to an isolated reform school for wayward Prodigium, supernaturally gifted teenagers, where she learns that an unknown predator has been attacking students.
Three years ago, Sophie Mercer discovered that she is a witch. Her non-gifted mother has been supportive, consulting Sophie's estranged father-a warlock-only when necessary. But when Sophie attracts too much human attention for a prom-night spell gone horribly wrong, it's her dad who exiles her to "Hex Hall", an isolated reform school for wayward Prodigium, a.k.a. witches, fairies, and shape-shifters.By the end of her first day, Sophie has three new enemies, a futile crush on a warlock, a tagalong ghost, and a vampire roommate. Worse, Sophie soon learns that an unknown predator has been attacking students. As a series of blood-curdling mysteries converges, Sophie prepares for the biggest threat of all: an ancient secret society determined to destroy all Prodigium, especially her.
