What do Heath and Buck, his dog, have in common? Many things: both are young, full of energy and live on the border between two worlds. Buck is half-wolf, half dog, born from a female wolf and a big Caucasian Shepherd. Heath is a young Native American: he belongs to the Lakota reservation and also to the "outside" world, white and technological. But there's more, even if the two do not know it yet: an overwhelming legacy, buried in distant memories. When the call of adult life becomes peremptory, difficult choices, revelations and encounters that will change their lives are envisaged for both. And the discovery of a hidden world, ruled by the magic that permeates all things.
