In the first major biography of Bonhoeffer in forty years, New York Times best-selling author Eric Metaxas takes both strands of Bonhoeffer's life?the theologian and the spy?to tell a searing story of incredible moral courage in the face of monstrous evil. In a deeply moving narrative, Metaxas uses previously unavailable documents?including personal letters, detailed journal entries, and firsthand personal accounts?to reveal dimensions of Bonhoeffer's life and theology never before seen.
