This exciting story, supported by fun facts, questions, and activities, follows two polar bear cubs born in a den dug by their mother deep under the winter snow of the Arctic. In spring, the mother and cubs emerge from the den and face the challenges of moving onto sea ice, where the hungry mother hunts for seals to eat. The cubs are given hunting lessons, ride on their mother’s back in the ocean, wrestle and play, and explore their cold habitat.
