Harry Potter goes to Hogwarts for his 3rd year. The school is guarded by dementors because Sirius Black, a wizard who was thought to have killed thirteen people with a single curse, has broken out of the wizarding prison. Harry and Hermione Granger find out that he is innocent and is Harry's godfather. Hermione has a time-turner and turns back time, and she and Harry save Sirius Black, who escapes from his death on a hippogriff, a half-eagle, half-horse, Buckbeak, who was supposed to be executed. NT 6/26/08 I thought this book was one of my favorites in the Harry Potter series. I really enjoyed all the action and suspense. I would recommend this book to all of my friends because the descriptions of the characters were so good that it made you feel angry or happy. AC 6/20/08
