The previous post made me think: What are the best books by great prolific writers? I mean, you can hardly tell someone to try CJ Cherryh — you have to give them a pointer toward a particular title that makes a great intro to her work, right? And the same with all those other prolific and super-prolific authors out there.
For me, some would be (in the order they occurred to me):
CJ Cherryh — the Chanur trilogy and Cuckoo’s Egg.
Patricia McKillip — The Riddlemaster trilogy and The Book of Atrix Wolfe and The Changeling Sea.
Martha Wells — The Raksura trilogy, still my favorite of her books so far.
Gillian Bradshaw — Beacon at Alexandria
Guy Gaviel Kay — The Lions of Al-Rassan
Terry Pratchett — Nightwatch
Sharon Shinn — the Safe-Keepers trilogy, The Shapechanger’s Wife
Tim Powers — On Stranger Tides
Ursula K Le Guin — The Tombs of Atuan
Tanya Huff — the Valor series
Any of you have specific title suggestions for prolific authors other than Smith?
