One of my favorite short novels of all time.
I remember I got it on sale because it was damaged a little bit. I was already captured with the title. The story consumed me. I read all of it in one hour without blinking :)
It is pretty morbid, but the horror lies in the reality of this story. With the circumstances surrounding this plague, I believe this is the way our world would actually go. Animalistic survival skills would prevail.
And can I blame the people.. Not really. It really is a horror.
