In the thin air above Switzerland, on the sheer rock-and-ice wall known as the Eiger, an American climber is about to embark on the most perilous and meaningful ascent he has ever undertaken: an attempt to scale the legendary mountain that took his renowned father's life. His extraordinary journey will take him from his home in Oregon to Europe's majestic mountain range, the Alps, where he will witness the amazing feats of engineering that forged bridges, tunnels and charming villages amidst the peaks; where he will learn about the life-saving science of avalanches; and where he will confront his darkest fears and greatest potential as he climbs to honor his father, who taught him to love Switzerland, mountains and life itself.
