school friend, magic, time travel released between 2000 and 2007

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.
