Yes, he’s the master of horror.
I’ve read over a dozen of his books now, and while some are better than others I enjoyed them all. This is one of the better ones. At 1100 or so pages, it took a while to finish, but even at that length I didn’t find much filler. There was one scene that I didn’t really like but overall I liked it a lot and really got to know and care about the characters. I liked the way he switched back and forth between them as kids and as adults. Sometimes you had to read a bit to know which was which. Clever. And Mr. King was very descriptive with being too long-winded. He really does know how to write.
