To avoid confiscation of his beloved ship the Witch, Harry agrees to a quick evacuation of a trio of refugees from the doomed Hong’s World. Destination – Maracanda, an azlaroc-type body, a curious non-planet where geography seems more like geometry and the soil itself can be a drug.

With help from ‘goodlife’, the berserkers could turn the strange combination of neutron star, black hole and Maracanda’s extra-ordinary geography into massive galactic destruction.

Across galactic timelines and landscapes, earth-descended humanity continues the fight against non-living, life hating Berserkers. Along with powerful allies of plants, sea creatures, computerized personalities, mythic men and a fictional detective, life struggles against its unliving foe. In cleaver hands, even the foibles of human personalities can be used against the unliving Berserker foe. Berserkers are automated warships, made by an unknown race to fight in an interstellar war that had been over ages since; they have outlasted their original enemies and their makers as well, having been programmed and equipped to rebuild and reproduce themselves. Still trying to carry out their originally programmed task, they made age-long progress across the spiral arms, leaving nothing living in their wake. This volume of fourteen tales, together with the Berserkers The Early tales, constitute a complete collection of Saberhagen authored Berserker stories. The stories The Bad Machines and Servant Of Death have not appeared previously in any Saberhagen collection.
