Dragged into a secret holy war between man and the legions of Hell, cross is trained as a battle-priest and spiritually ordained. He bears the Devil's mark, not by choice, but by fate-making him both the greatest threat and the last hope for humanity. Alongside Elira, an occult theologist with secrets of her own, he journeys deep into the Vatican's catacombs to uncover the truth behind 14 mystical seals that keep the Devil and his army imprisoned.
As ancient sigils fail and the seals begin to break, Rome becomes the battleground for angels, demons, and corrupted priests. Cross must battle not only monsters in flesh, but also spiritual torment, inner doubt, and betrayal from within the Church itself. With each broken seal, Hell leaks further into the world, and it becomes clear: ceoss is not just fighting the Devil-he may be the very key to unleashing him.
In a race against time, holy fire, and damnation, Rourke must decide whether to save the world by sacrificing his soul, or let it burn by embracing the darkness within him. The final seal can only be closed by a willing soul-and in the ashes of faith, a name must be written in dust.
