H. Beam Piper

Initially serialized in Analog magazine between 1962 and 1963, Space Viking takes place after the events of H. Beam Piper's earlier serialization, The Cosmic Computer. Space Viking is a classic space opera : what begins as an interstellar tale of revenge turns into a swashbuckling adventure yarn, and finally into a meditation on empire-building and galactic governance with direct allusions to our modern history.
This richness of content makes Space Viking a unique read. The reader begins by expecting a lighter sci-fi adventure, and early on the plot delivers ; but as events transpire, the reader is deftly drawn away from action scenes and into a more nuanced discussion on governance and human nature.
