TWO PLANETS CLASH FOR LUNAR TREASURE! Gregg Haljan was aware that there was a certain danger in having the giant spaceship Planetara stop off at the moon to pick up Grantline's special cargo of moon ore. For that rare metal--invaluable in keeping Earth's technology running--was the target of many greedy eyes. But nevertheless he hadn't figured on the special twist the clever Martian brigands would use. So when he found both the ship and himself suddenly in their hands, he knew that there was only one way in which he could hope to save that cargo and his own secret--that would be by turning space-pirate himself and paying the BRIGANDS OF THE MOON back in their own interplanetary coin. Here is a science-fiction classic, as exciting and ingenious as only a master of super-science could write. Born in 1887, Cummings acquired insight into the vast possibilities of future science by a personal association with Thomas Alva Edison. During the 1920's and 1930's, he thrilled millions of readers with his vivid tales of space and time. The infinite and the infinitesimal were all parts of his canvas, and past, present, and future, the interplanetary and the extra-dimensional, all made their initial impact on the reading public through his many stories and novels.
