Many millennia ago, in the dark depths of the Galaxy, two alien races clashed to the death, completely exterminating each other. The only legacy of these warlike races were the machines that ended their war. Killer machines. Berserkers. Intelligent bastion ships moved across the Galaxy, exterminating all life in their path, and little by little reached the borders of the newly-minted empire of mankind... The saga of space berserkers is one of the most famous science fiction epics of our time, it has become a generally recognized standard of the genre and brought to its creator Fred Saberhagen the love of millions of readers.
