Anyway, The Jungle is a classic by any measure, Dau is a classic, Downbelow Station and most of the rest of Cherryh's catalog, Horatio Hornblower, The Book of the New Sun, The Moon is a Harsh Mistress, A Canticle for Leibowitz, Hyperion, Riddley Walker, Blindsight... I could keep going all night. Listing these off, I realize that I forgot Dostoevsky in my list. Paulo Coelho should probably be there too.
