When They Came. When They Came, #1

I was never afraid of monsters-at least, not until They came: the visitors from outer space. Six years later, at the age of seventeen, I'm just about to graduate from school and declare my career of choice. The Midnight Guard-who protect our community from the vicious things that lie outside our walls-calls to me, and a shortage of applicants instantly lands me a spot in their ranks. But when I am bitten by an alien on a supply run, I begin to dream of things not of this world-and will soon find that my life is about to change forever.
