Berserkers are self-replicating killer machines, programmed by an ancient race to be the ultimate weapon of war. Something went wrong. The weapons now plagued the universe following a single mandate: kill all life, especially earth descended human life.
Harry Silver, spaceman extraordinaire, has a well earned reputation as the galaxies most successful Berserker fighter. However, recently during a battle with Berserkers, he lost his beloved starship The Witch of Endor.
Mr. Cheng, one of the universes wealthiest businessmen, is offering Harry the ship of his dreams, if Harry will undertake an almost certainly suicidal hostage rescue mission. Harry is reluctant, until he learns his wife and son may be among the hostages.
On his mission, Harry encounters a number of humans and machines whose ethical programming has gone astray.
Battles of wit and cunning accompany Harry's struggles.
