Dana-there actually is no relation between Sleep and Sematary, I just mentioned the latter because it was my 1st King book and it freaked me out, and the former because I have just read that scene I'm referring to and it's a rough one. Sorry if I mis-led you there, but to my knowledge, Pet Sematary II is the only continuation of that story, and I don't believe King had anything to do with that movie.
Kingricefan-I hear you on the kid-torture thing. When I read that scene, it was so difficult because I kept picturing my own son in that horrific situation. I'm now continuing Sleep in the hopes that the True Knot get taken down bad for what they've done.
