What about Bag of Bones? That's pretty recent and quite good.
I liked Lisey's Story much better than Cell. Hated the ending of Cell and found the resolution of Alice to be without purpose.
In my opinion, good horror has to be character driven. It isn't scary if you don't care about the characters. The best horror should have a compelling plot in place even before the creepy stuff happens.
(t's a definitive stylistic tactic of King's, the italicized internal monologuing of his characters. Also, I would say that he uses foreshadowing much more than flashbacks.)
(This should go get it's own thread, practically. I didn't read any King when I was 6. See above comment regarding Chronicles of Narnia being too scary for me. . .)
