Wow. this is almost impossible to figure out since his bibliography is so extensive. I just read a few months ago "Under The Dome" and it was pretty good. I would characterize his books as having unbelievably good setups and starts, with a strong yet sometimes sluggish unraveling and the endings are really hits and misses. But the journey is so awesome, that even crappy endings like with "IT", the book is still awesome to me.

If I had to choose one particular book, I would gravitate heavily towards "Carrie", it is developed in such a striking psychological profile, that Mr. King must be a true pervert to be able to get so much into the mind of a teen girl. :P (Not even kidding that much). But alas, there is a book that I consider the epitomy of the darkness that can come out of Mr. King's mind: Black House.

Wow, did that book actually faze me and I can be quite callous at times. Mr. King in the Black House really has it for the little kids and really does gruesome stuff with them. Even I was like, um, sheesh take it easy, that's enough child destruction? I couldn't put that book down till I finished it. And to boot it was quite hefty, not quite as big as "Under the Dome" but almost reaching the size of "The Stand".

I have read 24 of his book with the notable exception of the "Dark Tower" series, which I never got into. In fact didn't even know anything about it until I read the "Black House" and some cameo appearances happen. I also have not read anything that is not horror or dark.

[SPOILERS AHEAD] Is that what he said? I think the movie ending was certainly better for humanity, while it sucked for our protagonist, while in the book it was an open ending, which could lead to any possible outcome (IIRC).

You should mention that your post is a bit spoilery, but yes, according to imdb : "climax and ending that Darabont says in the DVD commentary was endorsed by King as the ending King wished he would have thought of". I have the film on DVD but haven't checked the commentaries yet.

Well, I didn't really talk about any special events...and well, this being a Stephen King novel... :P
But I'll edit the post, just in case.

I'll be original. Dolores Claiborne. Great book.

Didn't read the thread, don't know if it's been mentioned, but The Stand is my favorite single book, with The Dark Tower being my favorite series by him.

I didn't know that the new series on CBS would be based off a Stephen King novel. I may have to check it out, even though I didn't find the commercials for the TV Series that interesting.

Firestarter. The movie wasn't bad, but the book is way better.

Edit: actually, since the OP says 'book' and not 'novel' I should probably add On Writing.

The book is definitely good stuff. Do it like I do it, when I used to see a Stephen King book adapted to film, I would run and get the book and read it. Under the Dome is good stuff, but it is long so you gotta sink your teeth into it. It is well worth it. At the end you develop emotions on most of the characters and are rooting for either their survival or demise. And yeah, true to King, some will survive and some will die that you won't imagine.

for me it is wizard and Glass

Just started Joyland, about twenty pages in; have to say it seems promising.

The Dark Tower series.

I'm not a big Stephen king fan, but I did very much like 'Salem's Lot

Firestarter, Gerald's game and Misery.
