In the Lanie and Deenie's final season under their mother's watchful eye, the lessons of the previous years must be remembered and practiced. From foraging for food, to travelling safely, to defending against predators, the cubs must grow up and prove to Mama Lucy they can make it on their own. Left alone soon after the winter hibernation, Lanie and Deenie are forced to find their way in the mountains. Their very survival depends on the lessons learned and how they respond to danger. Book Three - The Parting completes the cycle of the grizzly bear cubs and finds them well on their way to becoming independent, full grown bears.
