Another SK fan here. The Stand is still my absolute favourite. I've just gone back to the older books for the first time in many years, and I'd forgotten how good they are. Started with the Shining, Dead Zone, Salems Lot and now I'm halfway through Firestarter (tho not quite so keen on this one).
I felt he lost his way a bit with Gerald's Game, Liseys Story, Rose Madder and Dolores Claibourne, but I did enjoy Hearts in Atlantis and the Regulators , which I read back to back.
Under the Dome and Full Dark No Stars feel like a return to the older stuff, tho there is a telling difference between the pre- and post-accident works :(.
