Carrie, The Colorado Kid, Firestarter, Cell....there are more, but I'm sure you get the point...
I too have not read Needful Things, although I've seen the movie several times. Alsok I haven't read Cujo, Dead Zone, Dolores Claiborne, Firestarter, and the uncut edition of The Stand.
Faithful is the only King book I haven't read...and I'm ashamed to say I don't even own it.
I admit that I have never read The Dark Tower series. I don't own the books and if I ever get myself to read them, it will probably be because I can get the whole bunch, used and on paperbacks. I also never read the Roadwork french version which I own, because...sorry...it bores me to death.
Six stories is the book I dream of owning some day.Big Big Dream. My Little Pony and Battleground are two more I would like someday.
