A hidden war rages beneath the surface, as demons walk the Earth and a select few fight to keep them in the shadows where they belong.
US Marine Raider Troy Odell knows combat, but nothing has prepared him for the secret battle he’s now thrust into. As the only survivor of his team, Odell discovers that the war between demons and humanity is disturbingly real—and he’s one of the few who can keep it hidden.
But as Odell grapples with his new role, he learns their side is vastly unprepared for what’s coming. If he can’t adapt, everything—and everyone—he knows will be at risk.
Can Odell rise to face an enemy unlike any he’s known, or will darkness claim the Earth?
