The Land of Frozen Suns is primarily an action and adventure novel which takes place near the northern most reaches of British Columbia at the foothills of the Rocky Mountains.

Bob Sumner, after having been shanghaied onto a boat heading north up the Mississippi from his comfortable home town of St. Louis, is put to work on the "New Moon" and finds himself in the much less comfortable territory mentioned earlier, where he is forced to learn all about treachery, double-crossing, and finds his trust in fellow man questioned more often than he was accustomed to. At the same time, he finds himself needing to learn how to survive in an environment which seemed the antithesis to his old style of life. (Summary by Roger Melin)
