The Martyrs have suffered their greatest loss in over a century... A loss that could bring them to their knees. The Underground believed they were winning the war against the Sins, but reality came crashing down in a burst of blood and brain matter. Now, they've descended into a new layer of hell, their faith shaken, their confidence shattered, and Darius Jones doesn't know how to build it back. While the Martyrs look to Thorn for answers, the nightmare Wrath constructed leaves her alone and spiraling out of control. Darius tries to shore up the illusion that she can keep them all together, but he finds himself getting pushed further and further away from the very person he's trying to save - and hurting the Martyrs in the process. Then, a new kind of devil rears her feathered head. Suddenly, Darius and Thorn find themselves dragged from one existential threat after another. Their finances are attacked, their people hunted for a bounty, and it becomes more and more evident that something has to change. In a desperate attempt at survival, Darius stumbles upon the Underground's darkest secret... Salvation has been within their reach from the very beginning - if only they can grasp it.
