Berserker Man - Fred Saberhagen

SUMMARY: For countless millennia the dreadful Berserkerr fleets have ranged across the galaxy in a relentless war against all things living. Their equally relentless opponent has been one of the least evolved of intelligent species, for of all the starfaring races, only mankind still has the heritage and instinct of battle, facing the enemy of all life in battle after battle. Here are four of those battles in the war between humans and the powerful death machines. Berserker's Planet: When a Berserker, severely damaged in a great battle between the fleets of humanity and the exterminating robot ships, hides on a planet whose inhabitants are just entering a period corresponding to the middle ages on Earth, a cult arises dedicated to death and worship of the Berserker's mobile robots. A lone rebel, armed only with medieval weaponry, doesn't stand a chance-or does he? The Berserker Throne: Exiled from the Eight Worlds, a prince discovers an operable Berserker-and the secret code which will give him control over the ancient war machine. With its help, he may return to power-but can a mere human really control a Berserker? Brother Assassin: The Berserkers reach back through time to kill a pivotal scientist in a planet's history, and only Time Operative Derron Odegard has a prayer of stopping them. Berserker Man: Over a century after the Beserkers had suffered an overwhelming defeat, humans have become complacent. But the killer machines have repaired and rebuilt themselves, and this time may succeed in eradicating humanity from the galaxy-unless they can be stopped by a child who is half man and half machine.
