The critics have spoken—this New York Times best-seller is "impossible to put down!"  Teens and reviewers alike have fallen in love with Demonglass' humor, forbidden romance, suspense, and delicious paranormal fun. Sophie Mercer thought she was a witch, which was why she was sent to Hex Hall, a reform school for delinquent Prodigium (aka witches, shapeshifters, and fairies). But that was before she discovered she's a demon, and her hot crush, Archer Cross, is an agent for The Eye, a group bent on wiping her kind off the face of the earth. What’s worse, Sophie has powers that threaten the lives of everyone she loves. Which is why she decides to go to London for the Removal, a risky procedure that will either destroy her powers forever—or kill her. But once Sophie arrives, she makes a shocking discovery: someone is raising new demons in secret and planning to use their powers to destroy the world. Meanwhile, The Eye is set on hunting Sophie down, and they’re using Acher to do it. But it’s not like she has feelings for him anymore. Does she?
