Harry Potter and the Prisoner of Azkaban is the third, and possibly the best, book in the phenomenally successful, award-winning Harry Potter series by JK Rowling.

After just about surviving yet another summer with the dreadful Dursleys, the arrival of Aunt Marge is the final straw and, in a fit of anger, Harry casts a spell on her, causing her to blow up like a balloon. He fully expects to be expelled from Hogwarts for his blatant flaunting of the rule not to use magic outside term time, but the arrival of the mysterious Knight Bus and a meeting with Cornelius Fudge, the Minister of Magic, result in Harry enjoying the rest of the holidays in the wonderful surroundings of the Leaky Cauldron.

Meanwhile Sirius Black--one-time friend of Harry's parents, implicated in their murder and follower of "You- Know-Who"--escapes from Azkaban and this has serious implications for Harry. Back at Hogwarts, Harry's movements are restricted by the presence of the Dementors--guards from Azkaban on the look out for Black.

Stephen Fry's endearingly snooty vocal chords are a perfect match for Rowling's superb storytelling, and Fry manages to give even further depth to a complex and absorbing plot by adding an irreverent wit and a deep-rooted touch of class to a compelling and magical tale that, once heard, will never be forgotten.
