Invaded

They came here with a purpose..... A purpose to hurt and kill humans. Nothing more and nothing less than that.
It's been a nightmare for the last ten years just trying to survive and not be caught by 'Them'. Everyday is a struggle. Everyday someone new dies. Friends, family, people that you've grown up with all your life, gone in that split second.
In a world where you struggle to survive, it's hard to form any type of friendship or bond with anyone else. Not because it's impossible. You just don't wish to be hurt anymore. You don't want to watch anyone dear to you die all over again.
