Geoff St. Reynard was the pseudonym of US author Robert Wilson Krepps for most of his sf and fantasy work, though he wrote adventure tales under his own name, some for “slick” journals like The Saturday Evening Post. Today he is remembered mostly for two highly imaginative novellas, The Buttoned Sky and The Giants from Outer Space. In this book he has created a wonderful sci-fi/fantasy action and adventure story, in some ways resembling John Carter’s adventures on Mars. It was originally published in Imaginations Stories of Science and Fantasy in August, 1953. (Goodreads)
