Biography of X

Biography of X is a 2023 alternative history novel by American writer Catherine Lacey. The novel purports to be a 2005 biography of the musician and artist X, written by her widow, C.M. Lucca, as a response to an unauthorized and apparently inaccurate biography of her wife written after her death. The novel also depicts an alternative history to the United States, one in which in 1945 Southern states banded together to build a wall segregating them from the rest of the country and forming the Southern Territory, a place marked by extreme religious control.
