For 12 long years, the dread fortress of Azkaban held an infamous prisoner named Sirius Black, convicted of killing 13 people with a single curse. Now he has escaped, leaving a clue as to where he might be headed: the Azkaban guards heard Black muttering in his sleep, "He's at Hogwarts...he's at Hogwarts." Harry Potter isn't safe, not even within the walls of his magical school, surrounded by his friends. Because on top of it all, there may well be a traitor in their midst.
