Berserker Death (The Berserker)

Ages ago, perhaps before the human race even existed, two war-maddened races fought - and though both are extinct, their Frankenstein weapon, the Berserkers, robotic asteroid-sized warships, still follow their program. And now the relentless death machines have crossed the galaxy, to encounter an equally relentless opponent: humans.
Three complete novels set in a seemingly endless war against death itself: The Berserker Wars: the millennium-long battle between humans and the killing machines, with heroes, cowards, villains - and even a prankster; Berserker: Blue Death: one revenge-obsessed man fanatically pursues the great blue Berserker that men call Leviathan; and Berserker Kill: a Berserker has stolen a biolab filled with human zygotes. Can its pursuers discover its secret plan before it's too late?
