Voyage From Yesteryear

Invasion From Earth: Earth seemed doomed to a fiery death, so they colonized the Alpha Centauri system with children. But not everyone perished in Old Earth's War. Decades later a generation ship bearing a cargo of colonists -- and an army to protect them -- headed for the planet Chiron to reassert Earth's lawful control over the fledgling colony. Too bad the colonists didn't see things the same way. A deadly clash -- with supermodern weapons -- was inevitable as each faction sought to convert the other to the "right" way. imaginative technological extrapolation and startling scientific speculation -- the stuff for which James Hogan is acclaimed -- abound in this novel.
