Harry Potter and the Prisoner of Azkaban

Harry Potter is about to begin his third year at Hogwarts School of Witchcraft and Wizardry, together with his closest companions Ron and Hermione. Harry is eager to return to school after the summer break. (If they had to live with the awful Dursleys, who wouldn't?) But there's tension in the air when Harry arrives at Hogwarts. The school is under the protection of the eerie Azkaban prison guards due to an escaped mass killer on the prowl.
