The galaxy's most lethal killing machines have infiltrated human society, but humanity has a plan. The Berserkers, sentient and implacable robotic destroyers of all organic life, have deployed sophisticated units designed to mimic humans, aiming for a decisive, all-out assault. However, the humans, aware of this insidious infiltration, are preparing their own counter-offensive to thwart the mechanical menace.

This installment in the Berserker series continues the established conflict between humanity and the relentless, self-aware killing machines. The premise sets up a tense cat-and-mouse game where sophisticated androids designed to infiltrate and destroy are met with human ingenuity and preparedness. The narrative likely emphasizes strategic maneuvering and large-scale conflict as humanity attempts to outwit its mechanical adversaries. Readers familiar with Saberhagen's work can expect a continuation of the high-stakes, action-oriented science fiction that defines the series.
