As his fifth year at Hogwarts School of Witchcraft and Wizardry approaches, 15-year-old Harry Potter is in full-blown adolescence, complete with regular outbursts of rage, a nearly debilitating crush, and the blooming of a powerful sense of rebellion. It's been yet another infuriating and boring summer with the despicable Dursleys, this time with minimal contact from our hero's non-Muggle friends from school. Harry is feeling especially edgy at the lack of news from the magic world, wondering when the freshly revived evil Lord Voldemort will strike. Returning to Hogwarts will be a relief...or will it?
