Shortly after graduating from U.S. Army Ranger School in 2006, PFC Alex Blum took part in a bank robbery. This act confused and horrified Alex's relatives, who knew him as an upstanding young man with a high moral conscience, who had wanted his whole life to become a ranger. His cousin Ben, however, wanted to go deeper - what were the emotional and societal factors that led Alex to make this seemingly inexplicable choice? This stellar true crime story weaves through psychology, sociology, and even mathematics as the author makes every imaginable effort to understand the cousin he thought he knew. It's a deep and dark but ultimately life-affirming read, filled with unforgettable moments from the first page to the last.
