In Extreme, Emma Barrett and Paul Martin explore the challenges that people in extreme environments face, including pain, physical hardship, loneliness, disagreements, and the approaches taken to overcome them. Using many fascinating examples and personal accounts, they take a close look at the psychological impact on those who face these challenges, the traits that enable some people to succeed, and what we can take away from their experiences.
