Teeth!

In the ethereal dreamscapes between sleeping and waking lurks a being of profound beauty and unfathomably cruelty, an eldritch consciousness older than the angels and far more terrifying. Lurking by the bedside of every sleeping child, she takes their teeth and leaves in their place a single copper coin etched with chthonian letters - the currency of no earthly country. To young Forsyth Ward, however, the fairy has gifted far more than a coin. She has bequeathed to him the seed of an obsession which will carry him from the haunted hallways of his ancestral home, to the far corners of the globe, and beyond the limits of his own sanity. If the fairy cannot take his teeth, she will come for his soul.
