On their own, without the guidance or protection of their professors, the three friends must now rely on one another more than ever. But there are dark forces in their midst that threaten to tear them apart. Meanwhile, the Wizarding world has become a dangerous place for all enemies of the Dark Lord. Long-feared war has begun and Voldemort's death eaters seize control of the Ministry of Magic and even Hogwarts, terrorizing and arresting anyone who might oppose them. But the one prize they still seek is the one most valuable to Voldemort: Harry Potter. The Chosen one has become the hunted one as Voldemort's followers look for Harry with orders to bring him to the Dark Lord alive.
