The Godless: Seven Forges, Book V by James A Moore
The long war with the Sa'ba Taalor has ended, but the land of Fellein does not know peace - only ceaseless change. A spate of murders draw the interest of Darsken Murdrow of the Inquisition, until the hunter becomes the hunted. Andover Lashk of the Iron Hands seeks a home in a world in which he no longer fits. An unholy necromancer steals souls, makes sacrifices, and sows fear. And in the barren wastelands of the Wellish Steppes, the army of the Godless gathers. Driven from their homeland, abandoned by their deities, the Godless now follow the banner of a new Master, and are thirsty for blood.
