Remnant Population

Remnant Population is a 1996 science fiction novel by American writer Elizabeth Moon. The protagonist, Ofelia, is an old woman who decides to remain behind on a colony world after the company who sent her there pulls out. It was nominated for the Hugo Award for Best Novel in 1997. The main character, Ofelia, lives on a fictional planet colonized by Sims Bancorp company. When the company decides to leave after a newly arriving fleet is mysteriously killed by aliens, Ofelia opts to stay behind, doubting she will live through cryogenic sleep, and not wanting to abandon the place where her family is buried. Ofelia hides in the woods until the others leave the planet; no efforts are made to search for her due to her lack of value to the company. She lives alone in the village until a group of the planet's natural inhabitants make contact. She teaches them her language and technology, and they refer to her as a 'Nest Guardian', a revered caretaker role. When the existence of the species is discovered by other humans, scientists and military personnel arrive on the planet and come into conflict with Ofelia's perspective on how to interact with them
