Hestia
Author: C J Cherryh
 
They were living on the edge of the human world. Just . . .
Hestia was losing her grip on survival. Seven years ago, engineer Sam Merritt had believed his offworld skills could save the planet. Now he knew he'd been wrong. Merritt though, had little choice but to stay on Hestia - for its stubborn colonists he was their only hope.
Sam knew the task the pioneers set him spelt disaster. To build their dam he must break the planet's silent taboo. And we would be forced to rend apart the lands of Hestia's most mysterious creatures, and expose the truth her human settlers had long purged from their minds!
