Just finished the book and am curious what the object was that Ryan turns down in the last chapter. Would like to know if anyone figured out what the author was decribing and if it had anything to do with the unsolved case or in some way was summing up Ryan's character.
Just found info on the internet about land divinities. The carving on the object that Ryan refuses is of the Celtic god Silvanus.
He is the interface between Tribe and Land and between our world and the Otherworld. Through him goods can be passed from one realm to another, and valuable things can be gotten from raw Nature.
I think the author did give us an answer to the the past murders and also literally handed them to Ryan in order for him to get out of the woods.
