The Canyon of Bones - Mountain man Barnaby Skye takes work guiding wealthy Englishman Graves Mercer on an exploration of the Yellowstone and Missouri River valleys. Mercer has come to the American wilderness seeking thrilling, preferably salacious, material for British tabloids. He takes an ancient bone that's sacred among certain tribes - and the act may cost the party their lives. North Star - Barnaby Skye faces radical change as the wilderness vanishes, buffalo are slaughtered, and the government puts the tribes on reservation land. His family's struggle to adapt takes them from Montana to Wyoming, wrestling with the tide of settlers and the new settlements that dot the western plains and mountains.
