The start of this book offers a brief yet genuinely refreshing and rare glimpse into the Death Guard Legion before their corruption by Nurgle. We follow Nathaniel Garro, a captain of the Death Guard who is injured in combat and transported to the Eisenstein. There, he discovers the full extent of Horus's betrayal. What follows are several heart-wrenching scenes on Istvaan III and Garro fighting to save Keeler, Sindermann, and the remaining 70 survivors from the treachery. James Swallow's writing style is raw, visceral, and poetic—a perfect follow-up to Ben Counter's approach. While the ending of the book isn't as strong as the rest, it serves as an acceptable conclusion to to the quadrilogy. I can’t wait to read more books about Nathaniel Garro!

I really like the way of the storytelling in this series: You get the overall picture, and then with every new book a different perspective and understand why a specific person is there at the moment. This is again true for this fast paced book - without spoiler the introduction of another Primarch still fills me with awe. :)
