But Harry doesn't want to be protected. Even as the Ministry of Magic denies his claims, The Daily Prophet discredits him, and even Dumbledore won't look him in the eye, Harry grows more and more determined to fight his lifelong enemy Voldemort—if only he had the "weapon" the Order is guarding.

He's haunted by dreams of a heavy door at the end of a silent corridor, and a vision of his father and the young Severus Snape that changes everything he thought he knew about them. Even the joy of working with "Dumbledore's Army"—a group of Soon Harry will discover the true depth and strength of his friends; their boundless loyalty and unbearable sacrifices. His fate depends on them all.
