In the hidden wilderness of Green Hollow lives the Inhuman. Tied to the forest, Tobias does not remember the past and is content with an unremarkable present in which he has a house, a cat and a flock of dryads. But everything changes when an extremely curious and charming young man, Henry Silver, becomes the new owner of Green Hollow. Ancient secrets that would have continued to rest in forgotten tracts are brought to light, and Tobias has to reckon with his troubled past and the green magic of the forest, in the heart of which dark things are happening.
