When National Geographic Adventurers of the Year Amy and Dave Freeman marry, they set out on an unusual honeymoon: a three-year, 12,000-mile journey across North America. From Alaska’s Inside Passage to Florida’s Key West, they traverse the continent by kayak, canoe, dogsled, and skis, encountering wildlife, sublime landscapes, and harrowing challenges.

Along the way, the Freemans also bear witness to environmental degradation and climate change—from plastic-covered beaches to forest fires to retreating glaciers. And as they engage with Native and rural communities most impacted by the changes resulting from modern industrial society and meet individuals and organizations dedicated to protecting the natural world, their adventure deepens in ways they never imagined.

From the white-knuckle rush of paddling white water to the wonderment of dogsledding across a frosted landscape where caribou and wolves roam, North American Odyssey is a celebration of our interconnectedness to the natural world and to each other. Beautifully written, engagingly told, and inspiring throughout, Amy and Dave Freeman’s story is a clarion call for change in the way we live.
