All I really remember is that at some point, Harry? I think it's before third year it goes into a store. And he's looking at all the book he sees an alcove i'm the shopkeeper tries to keep him out. But he goes in anyway, and the books have no titles, and there's a lot of 7 that speaks to him, and it ends app being his book said about his life. And it helps, in some way, but I can't remember why. And I can't remember what and I know that he talks to remus and greengotts and sirius. And it helps them defeat voldemort faster. Any help would be appreciated thank you.
