When Sophie attracts too much human attention for a prom-night spell gone horribly wrong, she is exiled to Hex Hall, an isolated reform school for wayward Prodigium, a.k.a. witches, faeries, and shapeshifters.

After killing the leader of a clan of assassins and falling in love with his heir, a young sorceress discovers she is the one person to bring down the evil Empire that has been oppressing her people for centuries, and now, in the heart of the Empire, Ileni herself is the deadliest weapon the assassins have ever had.
