Harry Potter and the Letter from the Future

Away from his friends, dreaming and thinking about Cedric Diggory's death. Also, the Dark Lord Voldemort had been reborn and was free, although nobody believed it, at least most of them. The worst of all? Harry was at his uncle's house, unable to talk to his friends, unable to stop thinking about the things that had happened. Well, receiving a letter from yourself in the future changed things completely. And it wasn't a normal letter, it was a magical letter with knowledge of many things. This is another story with certain fandom clichés. Time travel? Something like that. Harry kicking ass? Of course, he's in it. A couple used many times? Inside the damn cauldron. Spells pulled out of the damn ass and a Dumbledore who can only watch as Harry does things his way. Oh, and also a Voldemort who can't oppose the child of destiny, how could I forget something so important?
