Vampires, Werewolves, and Archangels OHMY!

So, I'm writing a story. About vampires. And I finally have the outline done. I wana know what you guys think of it so far.

17 year old Evangelina {Evie} Cavitolo moves from New York to somewhere I haven't figured out yet so her family could be closer to her insane blind grandmother. While there, she must become accustomed to a few new things. First of all her parents start going and becoming extremely active in church, something of which they have never had the slightest interest in before. Not only that, but like every new student, Evie must make new friends.

Right off the bat, friendly and good looking Nick Canne asks her to sit with him and his friends at lunch. As she gets closer to them, she realizes that everyone is friends with them, and wants to be part of their little pack, except for one lunch table.

Full of quiet but beautiful people, this other group of friends stays as far away from Nick's posse, as well as everyone else at school. This doesn't stop people from talking about them though.

Evie soon realizes that this group of people aren't welcome in their small town, and she's curious to find out why.

Despite the fact that she's part of Nick's clique, the other clique is drawn to Evie, and she must choose a side.

It isn't until she's faced with this decision when she starts realizing that her batty grandmother may not be so batty afterall; that maybe her old folklore legends are really true, that maybe and possibly vampires and werewolves still stalk the earth today, and that Italy may have it's own secrets hidden deep inside it's depths that makes her question everything around her.

What if the bubonic plague wasn't really a plague at all; it was just the fact that archangles really did walk the earth, and one them saved someone? Someone who wasn't able to control the thirst for blood, and accidentally created a new species of human? Nobody knows what happened between the plague and the rennaissance for sure, and nobody knows how the plague was reigned in. What if it was the werewolves? What if there was a thousand year battle going on between vampires and werewolves, and Evie has just been thrown into the middle of it? If that's the case, where did werewolves come from? And what is up with that creepy church her parent's have been attending?
