In the war-torn Sabbat Worlds crusade, Colonel-Commissar Gaunt and his regiment the Tanith First-and-Only struggle for survival against the forces of Chaos. As the crusade to liberate the Sabbat Worlds continues, the Tanith are posted to an unforgiving new warzone – the fortress world of Jago. As the enemy assaults increase in fury, Gaunt and his men must face the terror of the present alongside the ghosts of their past, for only in death does duty end.
