David Roberts is the award-winning author of twenty-nine books about mountaineering, exploration, and anthropology, including Alone on the Wall which was written with world-class rock climber Alex Honnold, whose historic feats were featured in the film Free Solo.
A luminous work of exploration, both personal and historical, written by one of my very favorite writers of the American Southwest. This is a piercingly beautiful and eloquent book. -- Douglas Preston, #1 New York Times best-selling author of The Lost City of the Monkey God and Cities of Gold
