Demonglass (Hex Hall Series #2)

Sophie Mercer thought she was a witch. That was the whole reason she was sent to Hex Hall, a reform school for delinquent Prodigium (aka witches, shapeshifters, and fairies). But that was before she discovered the family secret, and that her hot crush, Archer Cross, is an agent for The Eye, a group bent on wiping Prodigium off the face of the earth.
