Outdoor journalist James Edward Mills’s book, The Adventure Gap, is a groundbreaking volume that is equal parts adventure story, history, and inspiration as it chronicles the first American all-Black summit attempt on Denali in 2013. Mills uses this momentous expedition as a jumping-off point to explore diversity in the outdoors, from Mathew Henson who stood at the North Pole in 1909 to contemporary adventurers such as polar explorer Barbara Hillary and rock climber Kai Lightner.
