We've all heard about the leakage of Midnight Sun right? Well, I have a theory that you may not have thought of.
Stephenie Meyer did not just come up with the idea of vampires like the Cullens, but in fact, she is one herself. They think of themselves as vampires, but they are actually a subspecies of the mutated dead. Real vampires cannot come out in the day, they cannot come in contact with garlic and they have fangs right? The dead featured in the Twilight series may in fact be a real concept that no human is willing to take seriously. Stephenie had released the secret of the vampires to the world and now the Volturi want her destroyed. They blackmailed her into putting the unfinished Midnight Sun onto the internet, so she could act all depressed. Then they could kill her and say that it was just a suicide.
Think about it, it just may be true.
And watch out, the vampires are everywhere!
