Tarrano the Conqueror by Ray Cummings

In TARRANO THE CONQUEROR is presented a tale of the year 2430 A.D.--a time somewhat farther beyond our present-day era than we are beyond Columbus' discovery of America. My desire has been to create for you the impression that you have suddenly been plunged forward into that time--to give you the feeling Columbus might have had could he have read a novel of our present-day life.
