In a salty, slashing style, Tristan Jones unfolds his extraordinary saga—a six-year voyage during which he covered a distance equal to twice the circumference of the world—revealing both a rich sense of history and an insuppressible Welsh wit.

With a singleness of purpose as ferocious as any hazard he encountered, Tristan Jones would not give up—even after dodging snipers on the Red Sea, capsizing off the Cape of Good Hope, starving in the Amazon, struggling for 3,000 miles against the mightiest sea current in the world, and hauling his boat over the rugged Andes three miles above sea level to find at last the legendary Island of the Sun. And beyond lay the most awesome challenge of all: the tortuous trek through 6,000 miles of uncharted rivers to find his way back to the ocean.
