On a freezing day in the arctic, two polar bear cubs venture outside with their mother. She teaches them how to use their claws so they don’t slip in their frozen world. Then she leads them across the sea ice, the only place to hunt for seals, their primary food. The bears need lots of fat to survive through the summer when the ice is gone and food is scarce. 

Best-selling author Brenda Guiberson gives young readers a fascinating glimpse into the world of the polar bear. Breathtaking illustrations by Ilya Spirin bring the rich details of the arctic to life.
