In 2000, Marc Wallert and 20 other hostages were taken by terrorists to a Philippine island and imprisoned in the jungle for 140 days.

20 years later, he describes the strategies he used to survive and what he learned from the experience. The jungle didn’t break him, but the day-to-day life that followed drove him to burnout. In order to better understand why, he set out to find answers by focusing on the defining moments of his life – the crises.

In his bestselling book, he explains effective strategies for both private and professional life that can help people get through crises and become even stronger as they do so.
