Wynn and Jack have been best friends since college orientation, bonded by their shared love of mountains, books, and fishing. Wynn is a gentle giant, a Vermont kid never happier than when his feet are in the water. Jack is more rugged, raised on a ranch in Colorado where sleeping under the stars and cooking on a fire came as naturally to him as breathing. When they decide to canoe the Maskwa River in northern Canada, they anticipate long days of leisurely paddling and picking blueberries, and nights of stargazing and reading paperback Westerns. But a wildfire making its way across the forest adds unexpected urgency to the journey.
