In 2010, Sarah Marquis embarked on a perilous journey: alone and on foot, she walked ten thousand miles across the Gobi Desert, from Siberia, through Thailand, to the Australian outback.Relying on hunting and her own wits, she traversed fever-haunted jungles and scorching deserts, braved harassment from drug dealers, the Mafia, and camp raids from thieves on horseback. Surviving dehydration, dengue fever delirium and crippling infection, Sarah experienced a raw and spiritual communion after three years of walking at the base of a tree in the plains of Australia.Through an inspirational journey, Wild by Nature explores what it is to adventure as a woman in the most dangerous of circumstances, and what it is to be truly alone in the wild.

Born in Switzerland, Sarah Marquis has travelled the world alone and on foot for twenty-three years, crossing the United States, Australia and South America. She has given more than three hundred talks in French and English, including talks for TEDand the Geographical Societyand has been profiled in The New York Times Magazine. National Geographic named Sarah an'Explorer of 2014'.
