Agree with you on Golden Witchbreed (Mary Gentle) but Ancient Light drove me nuts! If I'd been Lynne Christie I'd have killed the company woman within ten minutes so I've been chary of trying others by her. Banks has never done it for my either and I don't know Erikson but I understand he's a mate of Donaldson who I don't like either. And although I admire Terry Pratchet I find him dull and his characters boring !!!
Ursula le Guin (except when in extreme feminist mode) and Terri windling do it for me, so does Heinlein and quite a lot of Herbert especially Dosadi Experiment, Santaroga Barrier, Green Brain and the original Dune book but none of its sequels, and Roger Zelazny. I like some Anne Mccaffrey, some Sheri Tepper, some Patrcia Wrede, prob others but brain's awash. Asimov and Clarke can't write althlough they have good ideas, like in Naked Sun and Childhood's End.
May have a re-read of GOT after reading John's opinion, not read for 20-ish years ... wonder how I'll like them now ???
