Yay! I love Stephen King books! I love throwing my two cents in.
NO. The Dark Tower series CANNOT be read separately. It's just like a series of books, like Harry Potter or whatever, you won't understand what is going on if you don't start from the beginning.
I love that series. I love love love love it. One of my other favorite books is Tommyknockers, which is about an alien spaceship and how its "aura" affects everyone around it.
I liked Cell (until the end...), so I DEFINITELY agree with you.
I really liked The Stand. Everyone says how long it is, but I LOVE long books, and I think that Stephen King is awesome.
I love all the short stories, and everytime a new movie comes out, I always read the short story before seeing the movie (1408, Secret Window, etc)
Most of Stephen King's books aren't (I don't think...) personally scary...a lot of them are mental. For example, Gerald's Game.
Let's see, what else should you try.... I really like The Talisman (Black House is the quasi-sequel, but not as good, I don't think)
There's also Insomnia, but it's VERY out there.
I personally LOVED Dreamcatcher as a book, the "inside of the head" with the alien is SO MUCH better read than on a movie.
Shorter stories that aren't part of a collection : The Girl Who Loved Tom Gordon, Green Mile, Dolores Claiborne.
But yes. If you like Stephen King, I would definitely recommend starting out with some thing like Tommyknockers
. It's very King-esque without being too scary.
Then read some of his short stories and then go for The Stand and The Dark Tower series.
God, I love Stephen King books.
Just please....Stay away from Buick 8 and Hearts in Atlantis (except the first part that was made into a movie..)
I don't know WHAT King was thinking when he wrote those.
