Charlie Bone and the Castle of Mirrors

Charlie Bone returns to Bloor's Academy where threats await from all around, and he must seek help from a peculiar painting and his ghostly ancestors. Over 3.4 million Charlie Bone books are in print. Charlie's power is taking on a new dimension as he meets a new cast of characters, including Mr. Pilgrim's replacement, Tantalus Ebony, and the mysterious new student Joshua Tilpin, who appears to be magnetic. Charlie isn't the only one dealing with changes; Billy has been adopted by a child-hating couple called the O'Gres, who carry a gray bag of oaths wherever they go, pressuring Billy to sign an oath of obedience, and locking him behind a force field in an odd place called The Passing House. Will Charlie be able to rescue Billy and uncover the mystery behind Joshua's power?
