Lieutenant Colonel Allen Forrester receives the commission of a lifetime when he is charged to navigate Alaska's hitherto impassable Wolverine River, with only a small group of men. The Wolverine is the key to opening up Alaska, and its rich natural resources, to the outside world, but previous attempts have ended in tragedy.
Forrester leaves behing his young wife, Sophie, newly pregnant with the child he had never expected to have. Adventurous in spirit, Sophie does not relish the prospect of a year in a military barracks, while her husband carves out a path through the wilderness. What she does not anticipate is that their year apart will demand every ounce of courage and fortitude of her that it does of her husband.
