2553. With the thirty-year-long Covenant War finally over, the Office of Naval Intelligence faces old grievances rising again to threaten Earth. Angry and bitter colonists--still wanting to settle scores from an insurrection put on hold for three decades--crave justice...as does a man whose life was torn apart by ONI when his young daughter was abducted for the SPARTAN-II program. Black-ops squad Kilo-Five now find its collective loyalty tested beyond the breaking point when the father of their Spartan comrade, still searching for the truth about her disappearance, prepares to glass Earth's cities to get an answer. How far will Kilo-Five go to stop him? And will he be able to live with the truth when he finds it? The painful answer lies with someone long dead, and a conscience that still survives in the most unlikely, undiscovered place...
