In a distant future of Earth's galaxy, exotic castes of humanity coexist uneasily with descendants of humans who colonised the stars. Peace is often short-lived. Commander Morgan Roche of the Commonwealth of Empiresarmada delivers an AI to her superiors in Intelligence. Just before completion of this mission, she is ambushed on Sciacca's World but escapes and her survival becomes dependant on a castaway, Adoni Cane, an adept fighter without a past. Betrayed, and abandoned by those she has trusted, Roche must tread a path that forces her to question everything she has held dear. Just what powers does this AI have and does it have its own agenda? Morgan will prove to be a tough adversary and a skilled survivor.
