Kage Baker's first fantasy novel is the tale of Smith, of the large extended family of Smiths, of the Children of the Sun. They are a race given to blood feuds, and Smith was formerly an extremely successful assassin. Now he has wearied of his work and is trying to retire into safe obscurity in spite of all those who have sworn to kill him.

To get there, he agrees to lead a caravan from the inland city of Troon to the seaside city of Salesh. The caravan is dogged by murder, magic, and the brooding image of the Master of the Mountain, a powerful demon, looking down from his mountain kingdom upon the unwary travelers passing below.
