One is about an immortal girl going to a modern high school filled with demons, archangels, the occasional angel, and werewolves, as well as various other mythical creatures and such. The different species are each kind of representative of a clique: wolves are jocks, demons are goth, archangels- AKA demon wannabes- are emo, vampires are (as Bowling For Soup so eloquently put it in High School Never Ends) "all the total dicks, all the stuck up chicks- so superficial, so immature." And then some stuff happens that creates an actual plot, but I don't want to say because I have had people steal my ideas before. (Even the crappy ones.)
The other is about an archangel girl who was raised in Hell, but ran away to Earth at age fourteen. She has to make a decision as to whether she wants to become a demon and stay in Hell permanently, and wed this total ASS that she's engaged to by her parents- or stay on Earth, not marry the guy, and live a short life, most likely ending up in Heaven with the guys she made fun of for so long in the end. The plot twists are surprising, as is the ending.
I'll notify you if we ever get first the first few chapters :)
In the meantime, check out some of my- ahem- illegal fanfictions. Well, they aren't illegal as long as you put a disclaimer since Rowling gave fans permission to write them, but I often- okay, almost always- forget the disclaimer.
