Suddenly projected to Mars, John Carter found himself captive of the savage green men of Thark. With him was Dejah Thoris, lovely Princess of Helium. And between them and rescue lay a thousand miles of deadly enemies and unknown dangers.
“Might it really be possible—in fact and not in fancy—to venture with John Carter to the Kingdom of Helium on the planet Mars?”—Carl Sagan
