After hearing about the Ender’s Game adaptation, it struck me that very few books have won the two most prestigous prizes in Fantasy/Sci-Fi literature - the Hugo, given out by the World Science-Fiction Society, and the Nebula, awarded by the Science Fiction and Fantasy Writers of America.
They are:
Dune, Frank Herbert (1965)
The Left Hand of Darkness, Ursula K. Le Guin (1969)
Ringworld, Larry Niven (1970)
The Gods Themselves, Isaac Asimov (1972)
Rendezvous with Rama, Arthur C. Clarke (1973)
The Dispossessed, Ursula K. Le Guin (1974)
The Forever War, Joe Haldeman (1975)
Gateway, Frederick Pohl (1977)
Dreamsnake, Vonda McIntyre (1978)
The Fountains of Paradise, Arthur C. Clarke (1979)
Startide Rising, David Brin (1983)
Neuromancer, William Gibson (1984)
Ender’s Game, Orson Scott Card (1985)
Speaker for the Dead, Orson Scott Card (1986)
Doomsday Book, Connie Willis (1992)
