Voyage from Yesteryear (Paperback) James P. Hogan

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 don't see things the same way. 

A deadly clash- with supermodern weapons- was inveitable as each faction sought to conveert the other to the 'right' way.
