Interesting. Perhaps a spin off thread could be "Mainstream Authors with SFF One (or Two) Hit Wonders".Tevis is hardly relevant - he wrote two sf novels, the second of which, Mockingbird, is in the Gollancz SF Masterworks series. He also wrote The Hustler and The Color of Money, which are better known.
Thinking:
Margaret Atwood
PD James
Kate Wilhelm
