Trap-Lines North is the story of that winter. So realistically does Stephen Meader retell it that the reader is virtually taken into the woods with Jim in the fall. He tramps from line camp to line camp, followed by the staunch old sled dogs, Bruno and Pat. He sleeps in rough pole lean-tos, eats moose meat, catches fish through the ice, and from time to time feels a chill along his spine when he comes upon the tracks of the lone gray killer---the biggest wolf in Canada.
