Reading Ciaphis Cain books is always a treat for myself. This book easily joins the rank of my list of good Warhammer 40K books. The action is great, the conversations are meh but who cares Cain is blasting heretics!
In this sixth book of the series Cain is shown as a teacher and mentor of the training facility for future commissars. He is trying to instill his way of being a commissar into them and sees the kids picking it up slowly. The planet is attacked by an heretic invasion fleet. Cain takes up arms again and starts fighting for the planet.
