Kanyenke discovers that John and Nonahkee are in love. John and Kanyenke soon ally with the French in the Seven Years' War to continue fighting against Warwick. When Colonel George Washington tells them that Warwick is a renegade and from the British, John agrees to help them track him down. John's mercenaries and Washington's forces destroy Warwick's base in the Great Lakes region, where John finds Stuart's decapitated body. John and Kanyenke continue to pursue Warwick to the Rocky Mountains, where they intercept Warwick's supply train and destroy a fortified Circle base. Warwick and his troops flee even farther west to Colorado, where they have allied with the Russians.

Amelia, Kanyenke, and Cooper chase Beaumont through the mines and find a map to the Lake of the Moon. At the Lake, now a swamp, the three destroy a Circle base, after which one of Beaumont's wolves kills Cooper. Amelia, now wanting to avenge Cooper, learns from local Seminoles that an Inca city in Pacamayo Valley houses several barrels of the Fountain's water. Amelia and Kanyenke sail to South America and help Simón Bolívar defeat the Spanish. Bolívar offers them guides, and, with the Circle's army in pursuit, they make a
