Kallik is a polar bear from the Arctic Circle, Lusa is a black bear in a zoo and Toklo is a grizzly bear living in the Rocky Mountains. When the bears are separated from their families their lives hang in the balance. Drawn to each other by extraordinary circumstances, they must search for food and shelter in an increasingly hostile environment. Will they make it, or will they face extinction? This is the first book in a trilogy that explores the beautiful savagery of the natural world and the impact of human interference.
