Harry, Ron and Hermione return to Hogwarts for a third adventure and magic filled year in this follow-up to the first two Potter blockbusters. Harry comes face to face with danger yet again, this time in the form of escaped convict Sirius Black. In a bid for help, Harry turns to sympathetic Professor Lupin -- but will it be enough?
Everyone's favorite novice wizard, Harry Potter, continues his high-flying adventures at Hogwarts. This time around, Harry ignores warnings not to return to school - that is, if he values his life - to investigate a mysterious series of attacks with Ron and Hermione.
The end begins as Harry, Ron, and Hermione walk away from their last year at Hogwarts to find and destroy the remaining Horcruxes, putting an end to Voldemort's bid for immortality. But with Harry's beloved Dumbledore dead and Voldemort's unscrupulous Death Eaters on the loose, the world is more dangerous than ever.
