The returned

I'm a high school girl, living in the United States of America, I'm only 16, life is supposed to be great, right? I'm living in one of the wealthiest countries on the earth, expectations aren't half as hard as most other people.
Well, that's how it's supposed to be. I'm supposed to be getting drunk, and spending nights out with my friends, right? Of course, I would be doing that, if the United States hadn't been attacked and infested with what is called "The Daemonous infestation", but basically what everyone calls "The Returned" five years ago.
We don't know where they came from, why they're here, all we know is that they need to leave, and we don't know how to kill this infestation.
They claim to have been here before us, this is their home, we're the invaders. They look just like us, but they kill off quickly. Super speed, super strength, different levels of communication, and fangs, everything to describe a vampire.
Everything I saw in the movies, had now become my life.
