This was the sixth book in the Beast Arises series. It would have been easy to make this almost a throw-away information filler but I found the tensions in this book really made it work. The inter-play between the Iron Warriors and the Fists successor Chapters was palpable. It was like that awkward family gathering where you have to be polite to that relative that you have a mutual hatred with. For me that alone made this worth a read.
There was a lot of story in this book. A lot of converging threads hinting at massive violence to come. All the in-fighting and pettiness on Terra becomes impossible to stomach with an attack moon in orbit. There was some great ship to ship action but for me this book was all about the tension and whilst some of that was physical it worked so well because it was all about that interplay.
In short I really enjoyed this story and think it adds something different to the already enjoyable series.
