Directed by David Yates. As Harry Potter begins his sixth year at Hogwarts, he discovers an old book marked as "the property of the Half-Blood Prince" and begins to learn more about Lord Voldemort's dark past. Share it, use it, love it. As the Harry Potter series draws to a close, Harry's greatest adventure yet is just beginning and it arrives in paperback J. The story is quick paced and holding, and the characters turn out to be much more unpredictable.
