kahni said:I am surprised no one here has recommended Terry Pratchett and his wonderful Discworld series. Granted, Discworld is more humourous than anything mentioned in the OP, but Pratchett might be the most gifted author I have ever read. And he definitely tackles much more complicated issues in his later books. 30+ books in a series, all million-sellers, is hard to argue with.
I definitely made this thread so I could get recommendations much different than what I have been reading, so thanks!
