I am Slaughter

Shockingly good. It's amazing how much better 40k gets with a touch of Discworld-ish wryness mixed into the grimdark.

Ever since Rogue Trader, 40k books and fluff have subtly been buying into their own emo-seriousness to the point you now wonder if the creators actually get how ridiculously the Imperium's fascism contributes to the dystopian aspect of the setting. Abnett is one of the few Black Library authors that can spin a good turn of fluff and inject some vibrancy of 40ks origins back into the universe.
