Special Forces are used to crazy ops, but orbiting a black hole to slow down time and fight Earth's dirty battles in the future? That's new, even for them. But that's the mission for Owen Quarry, Anaya Pretorius, and the rest of COG, a company of elite, disgraced, soldiers from around the globe. They join a defrocked company commander, an AI warship with self-confidence issues, and a crew of misfit troupers on a dizzying time-quest: prove the concept of stationing armies in spacetime. And if they complete ten missions, they'll be redeemed as citizens in good standing. But the cost will be heavy -- in time and in souls. And as one of their own hunts them down and another rises from the past with a key to freedom, Quarry and Pretorius find that redemption and survival are two very different things.
