I believe occupant has read Dr. Sleep. If I remember right she liked it. I haven't gotten around to reading much of his newer stuff, other than some of his short stories.
I think it's kind of neat that so many of his books take place in Castle Rock or close to it. I like the way he would reference characters from other books in his earlier work. And a lot of his earlier work is just scarier than a lot of his newer stuff. I guess when you've written as much as he has it's tough to keep coming up with it. One of his scariest books, to me, is The Shining. And you're right, Dr. Sleep is the sequel to that.
Anyway, pretty good list you have. Mine would be all classic stuff of his, I didn't care for Cell and never read Mr. Mercedes either. I'd have to think about my list a bit.
Yeah I found that interesting that there's some mentions of his earlier books in his later books, it's true that it can be hard to get more ideas. The Shining was indeed scary, I can't wait to read the sequel of it however. I loved Cell because I love stuff with zombies so I loved it instantly. As for Mr. Mercedes it's a very good book, I also enjoyed that one.
