Query: Original Story

I got to admit I was drawn in by the premise of Blood Crazy. Adults go crazy one day and start killing children. It is one of the most original stories I have read.The characters are really developed, and the story moves at a good pace. You wont find yourself getting bored with this book. The ending was really satisfying, and it does leave room open for a sequel.I recommend this book for anyone into Sci-fi, Horror, or anyone interested in a completely original story.
