This richly detailed Mallory and Irvine book serves as both a tribute to human courage and an in-depth historical investigation into the expedition that changed the trajectory of high-altitude exploration. Drawing from rare archival materials, personal diaries, letters, expedition photographs, and eyewitness accounts, Tyler Long breathes new life into a century-old mystery. With a historian’s eye and an adventurer’s passion, Long delves into the climbers’ motivations, the cultural and geopolitical backdrop of the 1920s, and the technical and physical challenges that Mallory, Irvine, and their team faced in the unforgiving Himalayan landscape.

Tyler Long book goes far beyond the surface-level narratives to uncover the forgotten truths, overlooked evidence, and emotional heart of the 1924 climb. Through vivid storytelling, Long retraces their footsteps from the crowded streets of London to the treacherous heights of the Tibetan Plateau, weaving together the personal, the historical, and the speculative with compelling authority. Readers are invited to question the long-held assumption that Edmund Hillary and Tenzing Norgay were the first to summit Mount Everest in 1953—could Mallory and Irvine have achieved it 29 years earlier?
