A. Bertram Chandler - The Rim Gods

First published as part of an Ace Double (72400) along with "The High Hex" by Laurence M. Janifer and S. J. Treibich in 1969. Cover art by the late, great John Schoenherr, most well known for his depictions of "Dune" - I've just read today that he's recently died, so this is my small tribute.
