Gripping and often poetic, Alone Against the North is a classic adventure story of single-minded obsession, physical hardship, and the restless sense of wonder that every explorer has in common. What Shoalts discovered as he paddled downriver was a series of unmapped waterfalls that could easily have killed him. Just as astonishing was the media reaction when he got back to civilization. He was feted by the Royal Canadian Geographical Society and congratulated by the Governor General. People were enthralled by Shoalts’s proof that the world is bigger than we think.

Traverspine is not a place you will find on most maps. A century ago, it stood near the foothills of the remote Mealy Mountains in central Labrador. Today it is an abandoned ghost town, almost all trace of it swallowed up by dark spruce woods that cloak millions of acres. In the early 1900s, this isolated little settlement was the scene of an extraordinary haunting by large creatures none could identify. Strange tracks were found in the woods. Unearthly cries were heard in the night. Sled dogs went missing.

Over half a century ago, John Rowlands set out by canoe into the wilds of Canada to survey land for a timber company. After paddling alone for several days, he came upon "the lake of my boyhood dreams", which he named Cache Lake because there was stored the best that the north had to offer-timber for a cabin; fish, game, and berries to live on; and the peace and contentment he felt he could not live without.

On the last day of June, my bush pilot left me alone and without food in a wilderness rain forest of Southeast Alaska. He would return in September. For the next 10 weeks my survival would depend on foraging, hunting, and fishing on an island I would share with 1,600 brown bears.

Disappointment River is a dual historical narrative and travel memoir that at once transports listeners back to the heroic age of North American exploration and places them in a still rugged but increasingly fragile Arctic wilderness in the process of profound alteration by the dual forces of energy extraction and climate change.
