So, when everything went dark and monsters, literal monsters, fell from the sky, I had no idea what to do.Hey, I’m not your perfect dystopian heroine. Hell, I’m not even your everyday human.

One minute everything is on track, and the next… well, it’s the end of the world. My name is Lex, and I guess I hunt monsters now. Perfect.
