There is a door at the end of a silent corridor. And it's haunting Harry Potter's dreams. Why else would he be waking in the middle of the night, screaming in terror? Here are just a few things on Harry's mind: A Defense against the Dark Arts teacher with a personality like poisoned honey. A venomous, disgruntled house elf. Ron as keeper of the Gryffindor Quidditch team. The looming terror of the end-of-term Ordinary Wizarding Level exams ... and of course, the growing threat of He-Who-Must-Not-Be-Named. Harry Potter is faced with the unreliability of the very government of the magical world and the impotence of the authorities at Hogwarts. Despite this (or perhaps because of it), he finds depth and strength in his friends, beyond what he ever knew; boundless loyalty; and unbearable sacrifice.
