Black Fire

"Two soldiers in Napoleon's army retreating from his disastrous campaigns in Russia are separated from their unit by a Cossack attack and stumble across an isolated Slavic town, where strange and bizarre doings are afoot. The ancient town is deep, forbidden territory, the prison of a dark monster-god out of Slavic legend and nightmare, which seeks to use the newcomers to escape. An historical horror story in the vein of HP Lovecraft and Brotherhood of the Wolf."
