1966’s Rocannon’s World was Ursula K. Le Guin’s debut science fiction novel.
Semley’s world has been impoverished by taxes imposed by recent visitors from a far-off land. She is not reconciled to the loss of a family treasure, a necklace worth a kingdom. Her quest to reclaim the necklace takes her first to the dwarfish Clayfolk in their underground halls and then to the overlords who received it from the Clayfolk. The overlords kindly return her necklace.
Had this been a fantasy novel, all might have been well. But she is a native of Fomalhaut II and she is a character in a science fiction novel. Her quest has tragic consequences.
