Power of the U'Tanse — Henry Melton

The only other race that had rebelled against the Cerik, the Delense, had been totally exterminated, but they had left a legacy--their technology and a hydroelectric plant that had allowed the Free U'tanse to live and flourish. But when it was damaged, Joshua's people were without a source of energy to run their vehicles and filter their air. There was only one way to get the power they needed to survive--take it from the Cerik. But how could they do that without bringing down the wrath of the planet's top predators?

Henry Melton's generation-spanning Project Saga examines humanity's destiny, both in the Earth Branch where a nearby supernova destroyed our civilization and we were forced to rebuild with powerful new technologies, and in the U'tanse Branch where a psychically-gifted splinter of humanity, taken away as slaves, make their way on a world that can never be their own.
