" Werner likes to crouch in his dormer and imagine radio waves like mile-long harp strings,bending and vibrating over Zollverein,flying through forests,through cities,through walls.At midnight he and Jutta prowl the ionosphere,searching for that lavish,penetrating voice.When they find it,Werner feels as if he has been launched into a different existence,a secret place where great discoveries are possible,where an orphan from a coal town can solve some vital mystery hidden in the physical world. "
