Part 1 begins as 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, without the guidance of their professors or the protection of Professor Dumbledore, 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. Harry's only hope is to find the Horcruxes...

Harry Potter returns to Hogwarts for another year of schooling and learns more about the dark past of the boy who grew up to become Lord Voldemort. There was a time when Hogwarts was thought of as a safe haven, but thanks to Voldemort's tightening grip on both the Muggle and wizarding worlds, that simply isn't the case anymore.
