I really like the Discworld series (I believe I've read every single book), but I believe they're a different category than the GRRM books. The later ones start addressing some social issues, and it's great to see Pratchet tackle them (and using fictional species removes some of the ethical issues, one thing where sci-fi and fantasy help with thought experiments)
