Gaunt's Ghosts is a series of military science fiction novels by Dan Abnett, set in the Warhammer 40,000 universe. It was inspired by the Sharpe series of books written by Bernard Cornwell. As of 2019, the series spans 16 novels which document the efforts of the Tanith First, a highly skilled yet unappreciated light infantry regiment of the Imperial Guard, during the Sabbat Worlds Crusade. The protagonist is Colonel-Commissar Ibram Gaunt, one of the few political commissars of the Imperium to be officially awarded command of a regiment.
