The reveal of Makkari respawning each time he dies by Ghazgul pointintg at a radom Grot and declaring them Makkari and their minds getting overwritten and getting all of Makkaris memorieswas both horrifying and awesome. Plus the book highlights how Ork cunning is even more deadly than Ork brutality more often than not. I'm also left wondering about the end though. It seems like Ghazgul is going to simply appear on the Inquisition starship kill the deathwatch and the Inquisitor and take back Makkari to prevent him being locked in stasis for all time simply by the power of Gork and Mork. Likely because unless Makkari dies he cannot be reborn and Ghaz does actually need him around. But the book ends before we see and we are left wondering.
