Fifty thousand gun-toting paladins march behind him, all baptized in angel blood, thirsty to burn unbelievers.Only the janissaries can stand against them.

But ever since his wife disappeared, he spends his days in a haze of hashish and poetry.To save the kingdom, Kevah must conquer his grief and become the legend he once was. But Micah writes his own legend in blood, and his righteous conquest will stop at nothing.When the gods choose sides, a legend will be etched upon the stars.
