Harry is back in his fourth year at Hogwarts, fresh from the memories of Pettigrew's escape from him and Sirius Black has gone into hiding again. But a Ravenclaw has disappeared from the school castle and suddenly resurfaces with extremely advanced magical skills acquired unknowingly. Dumbledore doesn't believe its a good sign and the castle is under surveillance. A sense of sinister foreboding prevails. Can Harry survive another year at the castle? Or will powerful enemies make sure its his last year at his only home?
