Marco Siffredi was the first person to make a complete snowboard descent of Mount Everest in 2001, and was regarded by many as the world’s best snowboarder. But the following year in 2002, Marco mysteriously disappeared on Everest while attempting a more difficult route known as Hornbein Couloir, an unrelentingly steep, difficult to access route with a high failure rate. Using exclusive never-before-granted interviews with family and friends, Evans aims to solve Everest's greatest mystery in nearly a century while exploring Marco's pursuit of a dream, his love of freedom and adventure, and how his French family was forever altered by his loss. "Marco was a purist, an athlete drawn to the bold and dangerous. Jeremy Evans humanizes Marco in a way that makes his disappearance a cautionary, yet inspiring, tale of someone who lived with purpose. But like most great stories with daring protagonists, we wished Marco's life could have ended differently." —Jimmy Chin, Emmy Award winning cinematographer and co-director of Academy Award-winning film Free Solo “Marco was a beautiful human who lived life on the edge in Chamonix and in the Himalaya. He danced on that boundary of life and death every day. We will always miss him, but See You Tomorrow reveals another side of Marco we didn't know, the one of a kind, gentle and innocent soul who left us too soon." —Jeremy Jones, professional snowboarder "Gripping. Scary. A fascinating glimpse into the world of extreme athletes who risk everything to follow their passion, live by their own rules, and die without regret. Marco lived a high-stakes adventure at extreme altitude that defies comprehension." —Diedre Wolownick, author of The Sharp End of Life and the mother of rock climber Alex Honnold from the Academy Award-winning film Free Solo Jeremy Evans is a climber, snowboarder, award-winning journalist, and the author of The Battle for Paradise and In Search of Powder. Through his writing and adventures, he has connected with the most influential people in the climbing and skiing/snowboarding industries and encouraged them to tell their stories. This was most evident with subjects in the outdoor adventure field where Jeremy has been able to connect with climbers, skiers, and snowboarders worldwide.
