Rebels of Akrona — Gregory Urbach

To defeat the Arikhan invasion of Earth, Governor-General Grey Waters gave his life to destroy the alien battlecruiser Bellerophon. But he did not die. For seven years, he labored as a nameless slave in a mining camp twelve-hundred light-years from home, until an insurrection forced him to seek a new destiny. Now free of the masters, Grey leads his young wife and nephew into a hostile wilderness, pursued by unrelenting foes. But he has also swore an oath. The conquered world of Akrona will not remain conquered forever.
