Harry Potter and the Prisoner of Azkaban (Harry Potter Book 3)

As it turns out, Harry isn't punished at all for his errant wizardry. Instead he is mysteriously rescued from his Muggle neighborhood and whisked off in a triple-decker, violently purple bus to spend the remaining weeks of summer in a friendly inn called the Leaky Cauldron. What Harry has to face as he begins his third year at Hogwarts explains why the officials let him off easily. It seems that Sirius Black--an escaped convict from the prison of Azkaban--is on the loose. Not only that, but he's after Harry Potter. But why? And why do the Dementors, the guards hired to protect him, chill Harry's very heart when others are unaffected? Once again, Rowling has created a mystery that will have children and adults cheering, not to mention standing in line for her next book. Fortunately, there are four more in the works.
