The adventures of young Dan Laurent who goes a-voyaging with the voyageu Amable Benoit, stem from the rivalry between the Hudson's Bay Company and the American Fur Company. An orphan living with his uncle at one of Astor's posts on Mackinac Island, seventeen year old Daniel is anxious for the opportunity to go on a canoe trip. When the chance comes it is not an ordinary one. He and Benoit and a priest in disguise, Lachaise, must go northwest to Rainy Lake so that Malhlot, a surveyor taken captive by Hudson's Bay, can be replaced by his near-twin, Lachaine, and freed to give important information about the boundaries between the United States and Canada. But a hackneyed quality makes the trip a singularly dull one, its conclusion foregone and Daniel's secure future rather staid.
