The Witchfinder (The Deiparian Saga)

In a post-apocalyptic world where tyranny and medieval torture reign supreme and witch burnings are an everyday occurrence, a top Witchfinder must confront the very Church he serves when he learns of its dark past and twisted plans for the future.
The Church of the Deiparous rules with an iron fist and its rising star, Witchfinder Imperator Malachi Thorne, is committed to leading its cause. Thorne is a man on the fast track to greater things so when a convicted traitor and heretic escapes his grip, he won't tolerate it marring his perfect record.
As he pursues his quarry, he must confront demons, sorcery, and a cult of witches out for his blood. But when Thorne comes face to face with the Church's dark past and its twisted present, his faith is tested to its limits. Now Thorne must decide who and what he believes in-and what he will do about it.
