Pratchett.

I've just finished LOTR for the first time in several years (but then it's practically engraved on my memory).

Silverberg, Wolfe, van Vogt, Austen, Lieber, Moorcock, Iain M. Banks... Of course you re-read books. The plot may not fade, but the details do. Now what's more interesting, a skeleton, or the fully fleshed human being? If you enjoyed it first time, you'll enjoy it again... & again... & again...
