From the window of the small floatplane, fifteen-year-old Gabe Rogers is getting his first look at Canada's magnificent Northwest Territories with Raymond Providence, his roommate from boarding school. Below is the spectacular Nahanni River -- wall-to-wall whitewater racing between sheer cliffs and plunging over Virginia Falls. The pilot sets the plane down on the lake-like surface of the upper river for a closer look at the thundering falls. Suddenly the engine quits. The only sound is a dull roar downstream, as the Cessna drifts helplessly toward the falls . . . With the brutal subarctic winter fast approaching, Gabe and Raymond soon find themselves stranded in Deadmen Valley. Trapped in a frozen world of moose, wolves, and bears, two boys from vastly different cultures come to depend on each other for their very survival.After an airplane accident, fifteen-year-old Gabe, his Dene Indian boarding-school roommate Raymond, and the elderly Indian Johnny Raven are left stranded in the Canadian wilderness. The wise old man calls on his deeply rooted knowledge of the land to keep the tiny group alive, leaving the boys to battle nature alone when he dies.
