Probably The Green Mile for me, although the other couple of books that I guess would tie with that would be Misery and Christine, the first and second of his books that I read. But, to be honest, I've never actually revisited a Stephen King novel after I've finished it so it's hard for me to say which is really a favourite then, and those are three that I read when I was younger, so the memory of them is a little fuzzy in my mind. Either way, those are the three that come to mind. A fourth would be Dolores Claiborne, a book I at least recall spending a day on holiday reading; a difficult one to put down, that's for certain.

Favourite book I'm going to say Salem's Lot.

I also like The Dark Tower series, but which book in particular not sure. I probably like parts of each book, but each book isn't outstanding on its own.

Now you all got me wanting to play The Mist game, which we probably will never get to see because of licensing and that sort of thing. :)

Only normal one I ever read was Pet Cemetery and thought it was awful.

I loved the Dark Tower novels as a teen though, read 1-4 I guess. I remember reading 4 in class in high school, my teachers always let me read and ignored me. Funny.

I don't read novels much anymore though, the internet broke me.

Nightmares and Dreamscapes, and The Body from Different Seasons (good movie, too).

Most of his earlier works and i really love his Dark Tower series. Also everything he writes that autobiographical or as an intro to his books. I find that very compelling and unusually well written.

Choosing a personal favorite out of so many books (and i have read most of them) is very hard but "Duma Key" would be close since i read it when i had a very series reumatic attack and was in a pain that was so bad that i can't even recollect how bad it was. Since the main character also dealt with pain and his way of coping it came very close to home so i guess that's why it had a huge impact on me.

Another one that comes close is Hearts in Atlantis.
Yes i suprised me how much i liked this one. I didn't find the idea of it very engaging so i had postponed reading it a long time. I shouldn't have because it's a very enjoyable read.
Dreamcather is unfortenately just like many of his later work: highly enteraining and engaging for the first half and then i all falls apart...

Par for the course stuff like:

The Stand
The Shining
The Body (well the whole collection was good but that story in particular)

and like a couple of others have put, I LOVE the Dark Tower series, to me it is one of my favourite works of sci-fi/fantasy/etc. I love the blending of many of his works into one journey through his multiverse was such an enjoyable adventure. I love how it ends, it has a delightful twist that I won't spoil for those who haven't read it. :)

I kind of like Salem's Lot.
But of the Stephen King movies Shining is the best. Jack Nicholson in one of his best roles - and I wholeheartedly agree with him that he wants to kill that unnerving wife of his! *eg*

Interestingly enough, Stanley Kubrick was intentionally harsh, mean and critical to Shelley Duvall during production so as to get a better performance out of her. If she was anxious and upset both on- and off-stage, she'd give a more emotive performance. It worked, but Duvall wasn't particularly happy about it, as you could imagine.

I've read it. I was just discovering King (or rather - discovering horror) and was pretty surprised about this book (just after King's 4th past Midnight and Masterton's Djin).
And if anybody's curious about Randall Flagg's backstory, it's a book to read :)

Hmm... maybe Skeleton Crew. I tend to prefer his shorter stories, and the older stuff.

I have to admit I just don't like him as much as I used to, but I still buy everything he puts out.

I think the "horror" in his writing got over-emphasized; to me he's much more of a "human condition" writer, especially as the years have gone on. Unfortunately, I think he tends to generally overdo things, even his short stories now - that is, drag things out for pages that could be accomplished in one or two.

Around Halloween I always find myself coming back to him, but that's about it.

I read quite a lot of King when I was in my teens and twenties and still sometimes get an itch to reread them. Of all his novels I'd say the best in my experience is :

The Stand.

I think his short stories are also brilliant, particularly perhaps :

The Mist.

Both of these stories are, each in a different way, "end of the world" stories, which for some strange reason I find .... comforting ..... I also love Dawn of the Dead and I Am Legend for the same reason.

There are some brilliant short stories in Skeleton Crew and Night Shift : Word Processor of the Gods, Survivor Type, The Jaunt, The Ledge ....

A lingering recollection : Reading "The Mist" for the first time will always stick in my mind. I was still at school but I can't remember exactly how old I was. I was on holiday in The Algarve with my parents. Outside everything was blazing sunshine, clear distant views and the future, while by stark contrast in my imagination (courtesy of King's story) there was only an all-pervading mist, the end of the world, hopelessness .... The contrast between the world without and the world within only served to make the story more powerful and memorable. This is one of several memories I have retained of where I was, what the weather was like, what I felt like at the time - all of which are connected with reading.

Oh yeah, those are my favorite parts, more than the stories, even.

I quite dislike his most famous books, but I remember enjoying Carrie (which I don't know to be very famous).

I think it's also the only book by King that I've actually read. All the others were the movie versions. From those, I liked The Mist and Dreamcatcher. Oh damn, must've forgotten The Green Mile is also an adaptation of his book, that's a winner, I guess!

Have yet to read the Dark Tower novels, sadly.
