Polar Bear Journey — Debbie S. Miller

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.
