For the world Quixos is not alive anymore and following him is like chasing a ghost. Only Eisenhorn is certain of his survival and he has to prove it otherwise his fate will lead him to his downfall. To beat the enemy this time the man who is considered as a hero among the people has to adopt means which will make him look more as a villain.
Perhaps in the end he will become the kind of person which he used to hate at the start of his career. Dan Abnett takes the story to a bigger level as he did in Horus Rising and Xenos, the ways the hero adopts shock us as well but he is left with no other choice at all. Toby Longworth trembles in narration at the middle chapters however the climax is handled alright.
