A dramatic and inspiring adventure story based on the lives of trailblazing mountaineer Christine Boskoff and her partner Charlie Fowler. Edge of the Map traces Christine's life as a high-altitude climber and mountain guide - from a two-day climbing course while a Lockheed engineer in Atlanta to her remarkable leadership of Seattle's Mountain Madness guiding company following Scott Fischer's death on Mount Everest in 1996. She was a rarity at the time - a woman leading otherwise all-male expeditions. Despite challenges both personal and professional, Christine persevered to find freedom and a balance with nature on the earth's wildest peaks. And, in legendary Colorado rock climber Fowler, she discovered her perfect partner. Edge of the Map captures each step of the pair's story, culminating in their disappearance among the remote peaks of western China and the desperate search to find them which gripped the world.
