“The World Makers” by John C. Maxwell (aka, John Glasby). London: John Spencer & Co./Badger Books SF-3 (1958). Cover art by S. Nicholson.
From the back cover:
“Earth had been destroyed, but Man had built his colonies on Mars and Venus and the far-flung moons of Jupiter and Saturn. Mutation and forced breeding had changed these people from what they once had been and they were no longer really human.
“But for Clyde Lester, the last man of Earth, things were more complex and difficult. From somewhere in space, there originated strange radio signals which made no sense and could only come from some point beyond the orbit of Pluto, the outermost planet.
“This is a novel of the future, a strange, unguessable future and of one man’s endless efforts to discover the identity of these creatures from the stars who threatened the security and peace of the entire Solar System.
“Hunted from planet to planet, with death and suspicion ringing him round, he finally came face to face with these creatures from the Deeps, these invaders who meant to sweep in and occupy the blistered ball that had once been Earth. And the final revelation was the strangest one of all.”
