The Sick God of Rokar — Tim Niederriter

Saul has no idea what lies beyond the world gate, but there Luther flees. He and Olivia give chase through a city Saul never knew existed, hidden between worlds. The city of Rokar and its inhabitants are under threat from the same monsters that plague Saul's travels wherever he goes. Still greater dangers await Saul and Olivia in the belly of the city than at any point before. His former friends are near, but they have changed, and now assist Luther. Politics in Rokar is even deadlier than on Earth. The third part of the novel Hunter and Seed sees the race continue and hunters and makers pursue the seed.
