Harry Potter has lived under the stairs at his aunt and uncle's house his whole life. But on his 11th birthday, he learns he's a powerful wizard—with a place waiting for him at the Hogwarts School of Witchcraft and Wizardry. As he learns to harness his newfound powers with the help of the school's kindly headmaster, Harry uncovers the truth about his parents' deaths—and about the villain who's to blame.

Year three at Hogwarts means new fun and challenges as Harry learns the delicate art of approaching a Hippogriff, transforming shape-shifting Boggarts into hilarity and even turning back time. But the term also brings danger: soul-sucking Dementors hover over the school, an ally of the accursed He-Who-Cannot-Be-Named lurks within the castle walls, and fearsome wizard Sirius Black escapes Azkaban. And Harry will confront them all.

When Harry Potter's name emerges from the Goblet of Fire, he becomes a competitor in a grueling battle for glory among three wizarding schools—the Triwizard Tournament. But since Harry never submitted his name for the Tournament, who did? Now Harry must confront a deadly dragon, fierce water demons and an enchanted maze only to find himself in the cruel grasp of He Who Must Not Be Named.

Returning for his fifth year of study at Hogwarts, Harry is stunned to find that his warnings about the return of Lord Voldemort have been ignored. Left with no choice, Harry takes matters into his own hands, training a small group of students to defend themselves against the dark arts.

Harry, Ron and Hermione continue their quest to vanquish the evil Voldemort once and for all. Just as things begin to look hopeless for the young wizards, Harry discovers a trio of magical objects that endow him with powers to rival Voldemort's formidable skills.
