Harry, Ron and Hermione set out on their perilous mission to track down and destroy the secret to Voldemort's immortality and destruction – the Horcruxes. On their own and on the run, the three friends must now rely on one another more than ever... but Dark Forces in their midst threaten to tear them apart. Meanwhile, the wizarding world has become a dangerous place. The long-feared war has begun and the Dark Lord has seized control of the Ministry of Magic and even Hogwarts, terrorising and arresting all who might oppose him. The Chosen One has become the hunted one as the Death Eaters search for Harry with orders to bring him to Voldemort... alive.
