Lucifer in the Twilight

Straightforward blurb: A boy from hell arrives in Forks: Lucifer, who feeds on souls and humans. When the roles of predator and prey are reversed between Edward and Lucifer, their parallel paths begin to cross, disrupting the peace of Forks and the Cullen family. More lighthearted blurb: As Edward and Lucifer work together to fight the evil spirits invading Forks, something romantic gradually develops between them. Edward is trying to figure out how to pursue Lucifer, so he goes to ask Lucifer's family member, Raven Mist. Mist's answer: "Wash yourself, then arrange yourself on a platter." Lucifer is fretting over how to sweep Edward off his feet. He goes to ask his own family member, Raven Mist, for advice. Mist's answer: "Wash him, then arrange him on a platter." Edward and Lucifer both think Raven Mist is a real birdbrain, and its advice is even worse than the abstract maps it draws. Raven Mist shrieks and flaps its wings, smacking them both. "I'm just a bird! Sure, I eat souls, I'm powerful, and I know right from wrong! How am I supposed to know how to pursue someone? Why don't you ask me how to pursue a bird? Damn it!" [The timeline is all over the place... The story is from the bottom's point of view. No character bashing. Bella's talent will be slightly enhanced for the sake of the story, and it will end once Bella's problem is resolved. Be prepared for OOC. This is a short story written purely for fun. Everyone is just a side character. If I had to name the protagonists, I could probably only just barely call these three the main characters.] A nonhuman bottom who pretends to be good but is actually the source of all evil VS a vampire top who's cold on the outside but warm within, innocent and easy to fool in some ways, without realizing it.
