When the great influenza epidemic strikes Duluth, Minnesota, in 1918, Marven's parents know they must send their son far away to keep him safe from the disease. So the ten-year-old boards a train headed for a logging camp, not knowing if he will ever see his family again. In the great north woods, Marven finds a new world of towering trees, endless expanses of snow, and lumberjacks as big as grizzly bears. He feels very alone among the enormous woodsmen--until he meets Jean-Louis, the burliest jack of all, and they become fast friends.
