Description:

Harry Potter and the Prisoner of Azkaban is the third book in British author J.K. Rowling's best-selling series. Harry, Ron, and Hermione return to Hogwart's for their third year of school and befriend newly appointed Defense Against the Dark Arts professor Remus Lupin. Meanwhile, the wizarding world is gravely concerned upon learning the news that mass murderer Sirius Black has escaped from Azkaban prison. Black was the wizard that betrayed Harry's parents and caused their deaths at the hands of Lord Voldemort, leading many to suspect he will come after Harry next.

To protect the school and its students, the dementors - shadowy wraiths who are the jailers and executioners of Azkaban prison - take up residence on school grounds. However, Harry and his friends soon learn that there is far more to both Sirius Black and the dementors than meets the eye.
