the Eisenhorn trilogy is one of those series that hooks you from the first page. The chronological order starts with 'Xenos', where we meet Gregor Eisenhorn as an inquisitor hunting heresy in the grimdark universe. It's a fantastic introduction to his world, full of cosmic horror and moral ambiguity. The second book, 'Malleus', cranks up the stakes—Eisenhorn's hunt for a rogue inquisitor forces him to confront how far he'll bend his own principles. The trilogy concludes with 'Hereticus', where everything spirals into tragedy. It's brutal, personal, and shows the cost of his choices over decades.
What's fascinating is how each book builds on the last. 'Xenos' feels almost like a detective story, while 'Hereticus' becomes this operatic downfall. The way Abnett writes Eisenhorn's descent from idealist to radical is masterful. You see him justify darker actions with each book, like using forbidden knowledge or consorting with daemons. The supporting cast—like his loyal savant Fischig or the enigmatic Bequin—add layers to his journey. By 'Hereticus', even allies question if he's become the very thing he swore to destroy. The trilogy isn't just about order; it's about how obsession corrupts.
