When Sophie Mercer turned thirteen, she discovered that she was a witch. It's gotten her into a few scrapes. Her non-Gifted mother has been as supportive as possible, consulting Sophie's estranged father--an elusive European 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 decides her punishment: exile to Hecate Hall, an isolated reform school for wayward prodigium, a.k.a. witches, fae, and shapeshifters. By the end of her first day among fellow freak-teens, Sophie has quite a scorecard. Three powerful enemies who look like supermodels; a futile crush on a gorgeous warlock; a creepy, tag-along ghost; and a new roommate, who happens to be the most-hated person and only vampire on campus. Sophie soon learns that a mysterious predator has been attacking students, and her friend Jenna is the number one suspect. Meanwhile, Sophie has a more personal shock to grapple with. Not only is her father the head of the prodigium council, he's the most powerful warlock in the world, and Sophie is his heir. As a series of blood-curdling mysteries starts to converge, Sophie prepares for the biggest threat of all: an ancient secret society determined to destroy all prodigium, especially her.
