The remarkable follow-up series to the New York Times best-seller, Warriors.

Three bears from very different worlds are about to embark on the quest of a lifetime.

When the bears are separated from their families their lives hang in the balance.

Forced to rely on their instincts and drawn to each other by extraordinary circumstances, these bears must search, not only for the food that will keep them alive, but for a safe haven in an increasingly hostile environment.

Faced with killer whales, fiercely territorial bears, starvation and the ever-present danger of human intervention, Kallik, Lusa and Toklo are left with only one place to go ...But the journey is long and hard, and the bears are only young.

Will they make it to their destination, or will they face extinction?
