Valtierra, a city-state, is governed by archetypes. Every two years they choose twelve men and women to wear the masks and to become the Wise Old Man, the Fool, the Mother, the Harlot, the Warrior, and the rest of the council. But now Valtierra faces hunger, decay, and an enemy on their border. When the need for leadership is greatest, one mask is worn by a foreigner and one mask hides a traitor.
