From now on, for all the people of his world, he is an Intercessor, a mighty warrior who knows no fear. They see him as a hero, a savior... But who considers him a man? Only two of his companions, equally revered and rejected, are the beautiful healer Lisha and the crippled violinist Roger, whose music hypnotizes everyone who hears it...
