Books in the Third Testament series

Luka and his friends fight for survival in a post-apocalyptic Seattle filled with demons, ghouls, and savage scavengers who challenge even the soldiers of hell in their brutality. But everything changes when a young girl threatens to change the balance of power.

Conrad of Marburg and his companion Elisabeth continue on their quest for the Third Testament. But to find the relic they must first escape the dark island where they are held captive and then reach the monastery of St Luke, which seems to hold the answer to many of their questions.
