The sequel to 2017’s Dark Imperium and the second book in the trilogy, Guy Haley’s Dark Imperium: Plague War continues the story of Guilliman’s ongoing battle against the forces of his brother Mortarion. With the Death Guard rampaging throughout Greater Ultramar, Guilliman makes for embattled Parmenio where he hopes to bring Mortarion to battle and kill his corrupted brother once and for all. Forces from both sides of the conflict are drawn to Parmenio, from Mortarion’s daemonic allies to the great space station Galatan, while Guilliman’s determined secular stance is challenged by growing evidence of something (potentially) divine making itself known.
