Meeting the Past-Reading Harry Potter the Deathly Hallows

During the 6th book, Harry and his friends get transported back in time right. They find themselves in the Great Hall with a book to read called Harry Potter and the Deathly Hallows. Voldemort is giving Harry Potter a chance to find out how this whole battle ends. AU with ages but other than that I am trying to keep it as close to the books as possible. *Used to be Matdancer9*
