"Forty million years after the death of Earth, one man's brilliant mind lives on-although strangely encased in an indestructible metal body of a Zorome. Professor Jameson and the machine men of Zor continue their danger-laden explorations of the wonders of the infinite universe: In the kelp cities of a watery hydrosphere planet they encounter the race of the Plekne fish-men, eternally enslaved by the alien Uchke. In the core of a hollow world, the Zoromes discover a cavern of bones, picked clean by the flesh-devouring predators who feed upon the humanoid Aytans. And through the marvels of a time machine, Professor Jameson views the mausoleum of his planet's history: from the glorious birth of Earth as it splits from Sol, to its ultimate devastated end."; 16mo - over 5¾" - 6¾" tall
