I've read a ton of his books (but not The Stand or The Shining) but the ones I can keep reading over and over are his collections of short stories. Night Shift is excellent, but Nightmares and Dreamscapes is my personal favorite. Dolan's Cadillac is perhaps the best revenge story ever.
Night Shift contains a story that STILL scares me, to this day, I won't even read it. "The Boogeyman". It's insane that a grown man can be afraid of something as simple as a story, but damn if I'm not. Everyone says it's a story with two personalities, silly in the day, scary as hell at night. I read it on one of those sterotypical horror movie nights, home along, dark, raining. I didnt sleep so well that night
"The Mangler" always makes me wonder, especially working around factory machines from time to time

Was Jerusalem's Lot ever made into a full book? I was kind of intrigued by the short story in the book.
