The acclaimed national bestseller, welcomed on the cover of the New York Times Book Review--the first and only diary written by a still-imprisoned Guantánamo detainee. Mohamedou Slahi has been imprisoned at the detainee camp at Guantánamo Bay, Cuba since 2002. In all these years, the United States has never charged him with a crime. Although he was ordered released by a federal judge, the U.S. government fought that decision, and there is no sign that the United States plans to let him go. Three years into his captivity Slahi began a diary, recounting his life before he disappeared into U.S. custody and daily life as a detainee. His 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.
