When Echo Squadron is deployed to the mountains of Kazmira, Sergeant Samuel Carter expects a dangerous military mission—not a war beyond human understanding. A shattered veil has awakened ancient Watchers, supernatural beings divided between redemption and dominion. As soldiers vanish and impossible creatures emerge, Sam discovers that his faith is connected to extraordinary powers. With nations collapsing into chaos and fallen forces preparing for war, Echo Squadron must confront an enemy that guns alone cannot defeat. The battle for Earth has begun, and its outcome may reach far beyond time itself.
