I read all kinds of books (one of my friends jokes that I will read anything that holds still long enough), but sci fi/fantasy is my favorite. I also love books on anthropology and archaeology and other sciences.
This was one of the creepiest books I have ever read. No wonder my dad was a little shaky having me read Stephen King when I was younger. After reading this, I don't think I will let my kids pick up his books until they're about thirty!(When I have children to worry about, that is)
