|This article is about the novel by Dan Abnett; for the Inquisitorial Ordo, see Ordo Hereticus.|
Hunted by his former allies as a radical and enemy of the Imperium, Inquisitor Gregor Eisenhorn must fight to prove that he remains loyal as he tracks down a dangerous heretic whom the Inquisition believes dead, the dread former Inquisitor Quixos. As he grows more desperate for victory, Eisenhorn uses ever darker means to achieve his goals, but how far can he go using the weapons of the enemy until he becomes that very enemy, and no different to the traitor he hunts?
Inaccuracies in Cover Description
Despite stating that Eisenhorn is hunting Quixos, that does not occur in this book; rather, it occurs in the previous book Malleus. Hereticus details Eisenhorn's hunt to bring down a resurrected Pontius Glaw who has gained a body and now seeks to achieve godhood.
