Space Viking Author:H. Beam Piper A galaxy wide war had destroyed the Old Federation, leaving every surviving world on its own--and at the mercy of the Space Vikings.
Lucas Trask was one of these renegades--a warrior with a ship and crew terrorizing a thousand worlds. He was a man with an old score to settle and a very special mission to fulfill.
Space Viking is a favorite of mine. I like that civilization is portrayed as fragile in it, as it shows that H. Beam Piper has a real grasp of history. But it probably deserves a sequel to build the world out more.
