Fong's account of this dramatic journey tells a passionate yet nuanced story of the Selenge River and its tributaries. About the fish and wildlife that call the river home. About the human history of the region, from the Bronze Age to the fall of the Soviet Union. About the people who live in the basin now-from nomadic herders to construction engineers-and their attitudes toward development and conservation. About the old gods and legends that haunt the mountains. And about the disparate possible futures for one of the most starkly beautiful places on earth.
