Quietly it comes—the dark and chill of winter. And in the snow-covered fields and forests, the great northern plains, vast stretches of frozen tundra, and icy polar regions, wild animals have to survive day after day, night after night, out in the cold. How do they do it? Kids can bundle up and join award-winning author, illustrator, and naturalist Jim Arnosky as he follows the tracks of otters, beavers, moose, polar bears, killer whales, penguins, fur seals, and other creatures to discover more about their lives during this frigid season. Arnosky's stunning art includes five magnificent foldouts that reveal worlds under the ice and at the farthest, frostiest reaches of the globe.
