If you like Stephen King, reading The Dark Tower series should be on your list if you haven't read it. Most of his latter works reference Mid-World (Roland's world) in some manner, if only fleetingly. The Stand, another fave of mine, has a strong connection to Mid-World. In particular, Randall Flagg.
I'd love to see HBO do a massive The Dark Tower miniseries.
