He has no job and no plans for the future but the sound of an ancient musical instrument, the mouth harp, points the way. From the torrid coasts of Sicily, Diego journeys to the frozen flatlands of Yakutia in Siberia where he becomes part of a prophecy from a century ago. The “sound of happiness” is at last there.
