He survived a terrifying crocodile attack off Australia's Queensland coast, blood poisoning in the middle of the Pacific, malaria in Indonesia and China, and acute mountain sickness in the Himalayas. He was hit by a car and left for dead with two broken legs in Colorado, and incarcerated for espionage on the Sudan-Egypt border. The first in a thrilling adventure trilogy, Dark Waters charts one of the longest, most gruelling, yet uplifting and at times irreverently funny journeys in history, circling the world using just the power of the human body, hailed by the London Sunday Times as "The last great first for circumnavigation." But it was more than just a physical challenge. Prompted by what scientists have dubbed the "perfect storm" as the global population soars to 8.3 billion by 2030, adventurer Jason Lewis used The Expedition to reach out to thousands of schoolchildren, calling attention to our interconnectedness and shared responsibility of an inhabitable Earth for future generations.

Jason Lewis is an award-winning adventurer, author, and voice for global sustainability. He is accredited with being the first person to circumnavigate the Earth without using motors or sails: walking, cycling, and inline skating five continents, and kayaking, swimming, rowing, and pedalling a boat across the rivers, seas, and oceans. Taking thirteen years to complete, the 46,505-mile journey was hailed "the last great first for circumnavigation" by the London Sunday Times.

A frequent contributor to magazines (Men's Fitness, Sports Illustrated, Geographical) and travel books (Chicken Soup for the Traveler's Soul, HCI, 2002; Flightless, Incredible Journeys Without Leaving the Ground, Lonely Planet, 2008; The Modern Explorers, Thames & Hudson, 2013), Jason has set three additional records: the first crossing of the Atlantic Ocean from mainland Europe to North America by human power; first crossing of North America on inline skates; and first crossing of the Pacific Ocean by pedal power. He is a Fellow of London University, the Royal Geographical Society, and The Explorers Club, and has appeared on numerous television and talk shows, including The Tonight Show with Jay Leno (NBC), Good Morning America (ABC), and CBS This Morning.
