Revenge at Beta Colony — Harlan Finchley

When colonists from Earth landed on Kepler One the Keplians allowed them to stay on the basis that they abandoned technology and lived within a designated area of land. As a result for the next fifty years Beta Colony had no trouble until one day a spree of killings shattered their harmonious existence. Cameron Ford was appointed as sheriff to bring order, but he had no success until Luke Mitchell rode into town and offered his help. This mysterious stranger used his trusty six-shooter to deliver justice, but it soon became clear that he had secrets of his own and accepting his aid would change Beta Colony forever.
