I've read many of his books: Carrie, The Shining, Different Seasons, The Green Mile, Firestarter, Christine, The Talisman, It, Misery, The Mist, Hearts in Atlantis. Will read Dreamcatcher, The Dead Zone, probably Gerald's Game and Insomnia later. He generally creates good momentum and interesting characters, and especially interesting supernatural evil, but sometimes is a little too unserious (all the Lord of the Rings referencing in The Talisman, which near the end felt video gamish) or repetitive. I also don't really like his dismissive attitude to the fans.
I've read all the Stephen King novels with the exception of the Dark Tower series; I didn't care for them. I'm halfway through Under the Dome (very good novel).
^ I assume you mean April of 2012? Also, the book is a mid-quel of sorts - set between volumes 4 and 5, I think.
Joyland was recently released in trade paperback only. It's actually reasonably priced, though. I picked it up Under the Dome begins airing on June 24th And probably the most exciting news, Doctor Sleep, the sequel to The Shining will be released on September 24th.
Love King, had a great impact on me when I started reading. It was my favourite book when I was little, though The Stand is his best accomplishment.
Now there was this blurb where both he and Carpenter had dreams of a huge godlike being walking past. We saw a little of that in The Mist. Where did that quote come from?
