The battle for copper pits two of Montana's larger-than-life titans, Marcus Daley and William Clark, against each other in a clash over the resource that will power America's new age of electricity. In their quest to mine "the richest hill on earth," a bitter rivalry grows, driven by greed, riddled with scandal, and capped off by corruption so great that it fuels the passage of an amendment to the United State Constitution. Daley and Clark are responsible for developing a billion dollar industry, expanding railroads, and wiring a modern world.
