Query: As far as end of the world stories go, this one is good.

I got this in a used bookstore and was suprised by it. It is your average end of the world story except in this book the action never lets up. I actually give it 3.5 only because I thought the author ended it rather quickly and I was dissapointed in that because he really had some great characters in the book that I wanted to read more about and find out more as to the reasons of Armegeddon starting but these things still did not diminsh my enjoyment of this book.If you like fast paced, end of the world, fantasy-horror books then I recommend this one.
