After almost a decade of the single largest shakeup in Warhammer 40,000 history being stuck in a limited release campaign book, the Fall of Cadia is finally getting a novelization. By Robert Rath, who also did The Infinite and The Divine, one of my personal favorite novels of the whole Black Library lineup.
Very excited for this, hope they do a followup of the return of G-man and his fight with Magnus too.
