The true and fascinating survival story of the world's most distinctive
bear. One January, in a cozy, snowy den, a polar bear gives birth to two
tiny cubs. They weigh only a pound each, and they cannot see or hear.
After several weeks, the family begins its journey-a 1,500-mile trek
across the treacherous frozen landscape in search of food. Along the
way, the cubs learn to hunt, swim, and travel as they grow so that they
can eventually survive alone.
