K2 by Ed Viesturs

An unflinching memoir and mountaineering history that chronicles multiple expeditions on the world’s second-highest peak, blending firsthand accounts of high-altitude strategy, technical climbing, and survival with profiles of past climbers and the mountain’s lethal weather and terrain; it examines decision-making under extreme risk, the logistics and ethics of rescue at the limits of human endurance, and the emotional costs and motivations that drive people back to a place that has claimed so many lives.
