Translated from Czech, the story is rooted in Slavic mythology and has a strong Central European flavor to it. The setting is timeless and, if it were not for a small number of modern references, it would be easy to imagine the story taking place in medieval (or at least pre-industrial) days. It is in sum a Fairy Tale, in the Grimm's tradition with all the blood, gore, and brutality of which the original tales are full. Characters (or even motivations) don't really matter as much as the jostling for power and control, and the long arm of fate directing everything.
It's not really the type of story I am drawn to, but if you like dark and primitive horror, this unique and well-styled book makes a good read.
