During the past two years my twin brother and I discovered that we have Demon DNA; I snogged a Werewolf and a half-Vampire, fell in love with a Fallen Angel, discovered that I was some kind of messenger for an Archangel...and then my life really went to Hell. Now I'm afraid - of losing the people that I care about or losing myself to my Demon Blood. I need a miracle. Or a really big sword.
