In Harry Potter and the Prisoner of Azkaban, Harry, Ron and Hermione, now teenagers, return for their third year at Hogwarts, where they are forced to face escaped prisoner, Sirius Black, who poses a great threat to Harry. Harry and his friends spend their third year learning how to handle a half-horse half-eagle Hippogriff, repel shape-shifting Boggarts and master the art of Divination.
