Prince of Space, The, & Power

The second novel is "Power" by Harl Vincent. The days of hydroelectric dams were over. But there was absolutely no assurance during the endless days of the future that the use of cosmic power was going to remain perpetually in place. And with the change in the control of this power came, by natural order, changes in economic and even in social control--violently. For the destiny of the world, it depended largely upon that commodity known as "power" and the men--good or evil--who controlled it.
