This is the story of the trapper, Link Stevens, and his fearless snow dog, Chiri. It began when the trapper and his dog set out to rescue a naturalist stranded in the perilous Caribou mountains - the impenetrable storm-blasted heights from which no man has ever retumed. Forced to live by Stone Age methods, they relied on every resource of the dog's wild cunning and the trapper's woodlore. How they battled a killer cougar and bloodthirsty wolves, yet brought their man to safety, is a gripping, action-packed saga. It is also the stirring tale of the deep love between a loyal snow dog and his courageous trapper master.
