**The National Bestseller** From the acclaimed, bestselling author of Turn Right at Machu Picchu, a fascinating, wild, and wonder-filled journey into Alaska, America's last frontier In 1899, railroad magnate Edward H. Harriman organized a most unusual summer voyage to the wilds of Alaska: He converted a steamship into a luxury "floating university," populated by some of America's best and brightest scientists and writers, including the anti-capitalist eco-prophet John Muir. Those aboard encountered a land of immeasurable beauty and impending environmental calamity. More than a hundred years later, Alaska is still America's most sublime wilderness, both the lure that draws one million tourists annually on Inside Passage cruises and as a natural resources larder waiting to be raided. As ever, it remains a magnet for weirdos and dreamers. Armed with Dramamine and an industrial-strength mosquito net, Mark Adams sets out to retrace the 1899 expedition. Traveling town to town by water, Adams ventures three thousand miles north through Wrangell, Juneau, and Glacier Bay, then continues west into the colder and stranger regions of the Aleutians and the Arctic Circle. Along the way, he encounters dozens of unusual characters (and a couple of very hungry bears) and investigates how lessons learned in 1899 might relate to Alaska's current struggles in adapting to the pressures of a changing climate and world.
