When Russ Clagg was eight his father gave him a motherless wolf pup to care for. The Claggs, who owned a dog kennel, named the pup Gray. Soon Russ and the small, snarling bundle of fur were friends.
Now, seven years later, Gray is on the run. One of the Clagg's prize dogs is dead, and men are hunting Gray down. Russ knows the wolf is not a killer, but if he can't get Gray north into the wilderness the wolf will be shot. Together boy and wolf have a journey to make - a test of courage and trust.
