Harry Potter and the Prisoner of Azkaban J. K. Rowling The Harry Potter adventure continues, as Harry spends his third year at Hogwarts.

The formula still works, as the story of Harry Potter and his studies at Hogwarts continues.  The notorious criminal, Sirius Black, has escaped from Azkaban prison and Harry is once again in danger.  He also is forced to confront the Dementors--sinister prison guardians who search for Sirius.  The remainder of the cast from earlier books also shows up again, including Hermione Granger, Ron Weasley and, of course, Hagrid.
