After being excluded from Helen's family-tree school project because she isn't a human family member, Martha decides to get in touch with her own roots. What better way to do that than to live in the wild like her wolf ancestors? Martha succeeds in convincing the neighborhood dogs to join her pack, but getting them to stay is a different story. How can sleeping on the cold, hard ground and hunting squirrels compete with comfy armchairs and gourmet dog food dinners? If her dog pack deserts her, will Martha's best friend Helen welcome her back to the family?
