This third book in the series mixes accounts of early explorations in west and attempts to reach the Pacific through the "Wall" of Rocky Mountains, with an ongoing description of the breakdown of Canada into northern and southern sections. While the government in Green Bay attempts to win friends in the south, an American agent opens a new front in the conflict by bringing a band of men to attack Sioux villages in the west. Shawn Murphy happens to be in the west researching early French attempts to push past the "Wall" of mountains to reach the Pacific. His confrontation with the American agent and his "angry-men" nearly costs him his life.
