Rogue Berserker

Harry Silver has already had a lifetime of trouble from ordinary Berserkers, the automated killing machines programmed an age ago to denude the galaxy of life. Now when his own family is kidnapped, he faces a deviant machine, a good fit for some or all of the Galactic Dictionary’s definitions of
(1) A deceitful, double-dealing evildoer .. . (4) A fierce elephant or stamodont that has been banished from the herd . . . (10) Having a peculiarly malevolent or unstable nature . . . (11) No longer loyal, affiliated, or recognized, and hence not governable or accountable . . . erring, apostate. – Galactic Dictionary of the Common Tongue
Ordinary Berserkers armed with weapons powerful enough to kill an entire planet were enough of a nightmare. What worse deviltry will a killing machine gone rogue attempt-and even if Silver can stop it, will he ever see his family alive again?
