History has a habit of reaching out from the grave and reminding us of our species’ greatest failings.

Humanity’s Migration Wars which birthed the Commonwealth of Sovereign Star Systems were the deadliest and most destructive in history. But not everyone draws the same lessons from past atrocities that were burned into the human psyche. For some, our species must do anything to avoid another murderous civil war, including the overthrow of the current political system. For others, a rerun, minus the mistakes made the last time, would once more consolidate power in the hands of the central government on Earth.

When a reconnaissance droid uncovers a lost munitions bunker from the Second Migration War containing the most horrific biological and chemical warheads ever invented, Rear Admiral Hera Talyn of Naval Intelligence immediately grasps the deadly ramifications. She quickly dispatches Ghost Squadron’s Erinye Company to guard the discovery on Keros, an airless, dead planet with nothing more than a mining outpost, until the deadly payloads can be retrieved.

However, those who would use the forbidden weapons to achieve their own goals still have spies inside Fleet Headquarters and are also moving fast. But Major Curtis Delgado, Erinye Company’s commanding officer, uncovers deeper mysteries on Keros than just weapons of mass destruction and must race against time and secret enemies to prepare for an all-out assault. Because he knows that if the warheads fall into the wrong hands, history could repeat itself, this time as an even greater tragedy.
