From publisher blurb:
This adventure might end with your party having a new loyal friend, better than any human. Or it might end with your party being stricken down by a weird, incurable disease.
It takes place in rural Ireland during the mid-17th century. Still, even in the green forests, you cannot escape from the evils brought by men and the inthings which surpass human knowledge.
(the inset photo of the back cover ad is AI-generated art because to hell with trying to find a bunch of kids and a cozy lived-in room like that in Finland... not the main figure with the overalls though, that one we did a real photoshoot for... and frankly after the print version was done I regretted having the AI-image edited to fix the majority of the hand/finger oddities, it struck me only when it was too late that having the image being very firmly in the uncanny valley would have been more on-brand)
