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? Harry has a few things on his mind and of course the growing threat of He-Who-Must-Not-Be-Named. In the richest installment yet of J. K. Rowling's seven-part story, Harry Potter is faced with the unreliability of the very government of the magical world and the impotence of the authorities at Hogwarts. He finds depth and strength in his friends, beyond what even he knew; boundless loyalty; and unbearable sacrifice. .
