The atmosphere at Hogwarts is tense. There's an escaped mass murderer on the loose, even the Muggles have been warned. The sinister prison guards of Azkaban have been called in to guard the school and Harry, Ron and Hermione rapidly discover why all witches and wizards live in fear of being sent to Azkaban. Lessons, however, must go on and there are lots of new subjects in third year Care of Magical Creatures and Divination among others. Plus the delights of Hogsmeade, the only village in the UK entirely populated by the magical community.
