Roger Fork and his team—sarcastic AI Miri and mysterious Kyra—find themselves on the front lines of a war when the Empire mobilizes them against the Awakened King of Dust. From a rejected refuse worker to a "leading engineer" of the galactic front. Roger must use all his ingenuity to create a weapon against the invulnerable Guardians. Battles in outer-space ruins, dangerous landings on a deserted factory-planet, and an epic act of sabotage on the Imperial flagship await the heroes.
