All of Stephen Kings other works, are smaller worlds/stories within the Dark Tower 'multiverse'. Whilst some don't even mention anything to do with the tower, others have subtle hints. And one books dimension is visited in the dark tower series. They're all worlds connected to the tower. The Stand is the one with the most connection.
Best set of books ever. Blew my mind. The opening and finishing lines, don't want to spoil for anyone... but ooomaagawd.
Anyone read Under the Dome yet? I got it for christmas but haven't made a start on it yet.
This. But not all of them are. There is a list somewhere in the intrawebzz
that tells you which ones are and which aren't. This series is King's Magnum Opus and touches most of his other works. I need to go back and read the whole thing again someday...
