Myths are full of lies.

This is not one of them.

Fleeing the downfall of an empire, a mermaid and her plague doctor companion escape into the eerie shadows of a wintery forest.

Amongst the bark and snow they are drawn into ancient games for ageless children - a murderous hunt of blood and sacrifice - deep in the woods, where three who call themselves 'saints' rule over them all like gods.

Trapped in a feverish nightmare of masked monsters, stitches and surgeons, and needle teeth, the mermaid must embrace all of her cruelty and hungers to free the children.
