The acclaimed national bestseller, the first and only diary written by a Guantánamo detainee during his imprisonment, now with previously censored material restored. When GUANTÁNAMO DIARY was first published--heavily redacted by the U.S. government--in 2015, Mohamedou Ould Slahi was still imprisoned at the detainee camp in Guantánamo Bay, Cuba, despite a federal court ruling ordering his release, and it was unclear when or if he would ever see freedom. In October 2016, he was finally released and reunited with his family. During his 14-year imprisonment, the United States never charged him with a crime. Now for the first time, he is able to tell his story in full, with previously censored material restored. This searing diary is not merely a vivid record of a miscarriage of justice, but a deeply personal memoir---terrifying, darkly humorous, and surprisingly gracious. GUANTÁNAMO DIARY is a document of immense emotional power and historical importance.
