H. Beam Piper 
Space Viking 

Get set for rip-roaring adventure in this tale from the imagination of science fiction luminary H. Beam Piper. In the aftermath of a massive war, many once-developed planets have been reduced to rubble, and the few survivors have lost all vestiges of civilization. A group of so-called ‘Space Vikings’ have begun to roam the galaxy, snatching up everything valuable that has been left behind.
