Barnaby, a black bear cub, and Thor, a search-and-rescue dog, startle each other by a springtime mountain spring. After discovering that Thor is not a white bear ghost they become friends and happily begin imaginative forest adventures.

Each season has a focus, from gathering shed antlers and making whistles for Trade Day to getting an idea to build a log home deep in the forest the bears would not have to hibernate, and Barnaby and Thor could have snowtime adventures and enjoy the Season of Sharing.

After a joyous day of skiing and snowboarding, Barnaby and Thor warm themselves by the fire and know there will be more mountain adventures because, as friends, they dared to dream.
