Seventy-nine degrees north latitude 1 is near the top, at the cold edge of the world. In the winter, when temperatures plunge 2 below freezing, there is complete darkness at noon. During summer, the sun shines at midnight, there is no place to hide. Danger is everywhere. Life on Svalbard is intense, so was the hunger that burns inside this female polar bear. She eats seals that live on sea ice. But this spring she cannot find them, anywhere. The pack ice has not arrived. The bear needs food this summer, and she needs to store fat for the coming winter. If her icy world grows warmer, will she survive in the Arctic?
