In 2018, two couples set out on an expedition to Alaska's Hidden Mountains, one of the last wild ranges in North America. But as they neared the top of an unclimbed peak, rockfall grievously injured one of the team, leaving him stranded and in critical condition. Over the course of nine hours, the other three climbers worked to reach their companion, and they were joined by elite pararescue jumpers. With visceral prose, Michael Wejchert recounts the group's rescue and traces the emotional scars left in the wake of life-altering trauma.
