Boone Bragg is also stuck. With his parents on vacation, the management of Bragg Mining falls on him, and one of his advisors wants him as a son-in-law. One wrong move, and Boone will end up either offending an associate or getting married to a woman he can't endure.
While closing up a spent mine, Boone gets two surprises. One is an untamed farm girl who's trespassing with a pickax, and the other is the amazing crystal cavern that she's discovered. Suddenly Boone sees a way to overhaul the family business. With part of the cavern on Kentworth land, Boone makes Maisie a proposal that he hopes will solve all of their problems. Instead it throws Joplin into chaos.
