Blood, Flesh, and Tears - Robert Weber - Bog

Daemos stalks the skeletal streets of Viscrucia looking for a worthy victim. He finds it in the city's nightmares when a sinister Lord challenges Daemos to claim the unkillable in return for a chance at immortality. The crimson odyssey leads him to monsters, obscure religions, lust, and a transformation no human has ever survived. Something emerges from the depths of the Suffering eager to drag him there, but the Lord has other plans. A storm grows. Viscrucia evolves. More and more want Daemos's head. Flesh will be paid. Pain is just the beginning.
