When men learned how to break free from the Earth and travel across space to other worlds, they knew that they were coming face to face with the unknown. For a time, all went well; but when the first space-ships reached the moons of the frozen, giant world Jupiter, disaster struck. What was the peril that lurked there, bringing death to those who landed? Scientists could not tell, so they sent the one man who might be able to find out – Gregory Quest, Quest of the Spaceways, with his three companions, Lester Vane, Nigel Whipperfield and Professor Fell. All four knew that they were running into deadly danger, but had they realized what waited for them upon Callisto, the fourth of Jupiter’s twelve moons, even their courage might have failed them.

This is the first of a thrilling new stories of Quest stories by the best-selling author of The Boy’s Book of Space, etc.
