In Harry Potter and the Goblet of Fire, J.K. Rowling offers up equal parts danger and delight - and any number of dragons, house-elves, and death-defying challenges. Now 14, her orphan hero has only two more weeks with his Muggle relatives before returning to Hogwarts School of Witchcraft and Wizardry. Yet one night a vision harrowing enough to make his lightning-bolt-shaped scar burn has Harry on edge and contacting his godfather-in-hiding, Sirius Black. Happily, the prospect of attending the season's premier sporting event, the Quidditch World Cup, is enough to make Harry momentarily forget that Lord Voldemort and his sinister familiars - the Death Eaters - are out for murder.
