Strange question, but I'm just wondering abouty'alls opinions, since this came up with a convo I was having w some friends. The supernatural scene has been a huge hit. Vampire Academy and Twilight basically dominate vampires. Twilight has some good ground on werewolves, as does TMI. TMI sort of takes over the world of demons. Harry Potter dominates witchcraft. Percy Jackson has a pretty firm grasp on greek mythology, and where that lacks, there's the Covenenant. In your opinion, what are some areas of broad supernatural mythology that haven't really been delved into by YA authors?
