Hogwarts, once thought to be a safe haven, may no longer be safe. Harry suspects that new dangers may lie within the castle, but Dumbledore is more intent upon preparing him for the final battle that he knows is fast approaching. Harry will have to help him uncover a vital key to unlocking Voldemort's defenses, a critical piece of information known only to Horace Slughorn, Hogwarts' former Potions Professor. Dumbledore manipulates his old colleague into returning to his previous post with promises of more money, a bigger office and the chance to teach the famous Harry Potter.
