They are the leaders. The creators of the pack. She digs the den, where their young will grow. He patrols the territory and brings her food while she cares for the helpless pups. As seasons pass, and new litters arrive, the pack grows and all work together to raise the young. A wolf's piercing howl can carry up to 10 miles, raising goosebumps on even the most intrepid camper's skin. But the gray wolf is far from a simple predator. An incredible combination of teamwork and instinct has helped wolf packs survive, despite being endangered in most of North America. With a mother wolf and father wolf leading the pack-their family-together, the cubs grow and learn the skills they need to start their own pack someday. With stunning, lifelike illustrations and facts on each page for grownups or older children who want a deeper dive, this beautiful picture book is a monument to these majestic packs.
