Ring of Violence — Douglas R. Mason

Violence breeds violence. A chain reaction. An ever widening circle of inevitable cause and effect. As an observer, in one of the small communities in a desert of ash left by a new wave of volcanic disturbance, Boyd Lassen could condemn it. But events pushed him into accepting the attitudes of mind that are its root cause. He is condemned and left for dead. He makes a fantastic journey in a resurrected earth-moving machine. Finally, he sets out with the nucleus of a new community to found his own colony. Leadership brings out the violence which is latent in himself.
