Harry Potter and the Prisoner of Azkaban

Next title in the Harry Potter series: Harry Potter is a wizard. He is in his third year at Hogwarts School of Witchcraft and Wizardry. It's always a relief after summer with the Dursleys, however, Harry doesn't realise that this year will be just as eventful as the last two! 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. The Author: Jo Rowling lives in Edinburgh with her daughter Jessie. Harry Potter and the Philosopher's Stone was her first novel. She came up with the idea for Harry Potter when she was on a train. She is currently working on the fourth out of a potential series of seven Harry Potter books.
