Harry Potter and the Dealthy Hallows is the seventh and final book in J.K. Rowlings Harry Potter series. Voldemort is continuing to accumulate power and it is up to Harry, Ron, and Hermoine to find the remaining Horcruxes to defeat him once and for all. When the Death Eaters descend upon Hogwarts, it leads to a battle that will affect the future of the wizarding world forever.
When Harry comes to he’s surprised to find them in a forest, and Ron is soaked with blood; he's been splinched so a big chunk of his shoulder was missing, and Hermione healed the wound with some dittany. Hermione explains that one of the Death Eaters, Yaxley, grabbed hold of her just as she was Apparating them back toGrimmauld Place. He was taken along and she unwittingly let him into Grimmauld Place, which means they couldn’t go there. In a split second she Apparated them out of the house and into the place where they had camped during the Quidditch World Cup(Harry's fourth year in Hogwarts).
They have to stay in the forest now, since they can’t ever go back to Grimmauld Place, so Harry gets out their tent while Hermione casts protective spells around where they are.
While they’re in the tent they get out the locket and examine it. It feels immensely strange to them to be holding a piece of Voldemort’s soul, and the locket pulses slightly, as if it contains his heartbeat as well. Harry puts the Horcrux around his own neck to keep it safe and Harry can feel the metal heart pulsing on his chest, and irregular beat with his own heart.
That night, Harry is starving and dispirited. He’s not as elated as he thought he’d be after stealing the Horcrux. He has no idea how to destroy this one, or where the other Horcruxes might be. Suddenly, his scar sears with pain and he gets another vision from Voldemort. Voldemort has found the foreign wand-maker, Gregorovitch, and is torturing him for information about a thief that stole something from Gregorovitch many years ago. Harry is very surprised to see this, because he was sure that Voldemort had gone to Ollivander to find out why using a different wand (to avoid the pretection of Harry with the twin cores) didn't work becauseLucius's wand was obliterated by Harry's, when Harry's acted of its own accord. And so Harry thought Voldemort wanted to go to Gregorovitch for advice because maybe he was the better wandmaker. Voldemort, however, hadn't mentioned anything about the wands to Gregorovitch, so Harry was puzzled.
