I've read It, the Stand, Cujo, Salem's Lot, the Shining and a bunch of other King's horror novels. So far this is my favorite SK book. It's such a beautiful work of prose. King manages to ravishingly tie in a love story, a political plot, and supernatural powers.
I read the Dead Zone a few years ago, but it really stuck with me. I think a re-read is on order before I tackle 11/22/sixty three.
