I've heard a lot about this book and finally found a copy to read. I have to say I wasn't overly impressed. The kids are nasty, to be sure, especially Paul. He was a true psycho in the making. The other terrifying thing was that the youngest evil kid was only 9! And they were so nonchalant about everything, as if it was just a regular occurrence. That is what gave me the chills.
But, I just thought the story was too slow and rambled on a bit and I didn't care for the writing style. The copy I had, had formatting issues so it was a bit difficult to read and maybe that's what made it just an ok book for me. I did remind me of The Girl Next Door by Jack Ketchum, which I thought was much better.
If you're into the evil kids bit, this might be for you, otherwise you might want to pass on it.
