Dembski-Bowden is rapidly becoming my favorite WH40K author, with his easy, flowing style and ability to solidify a great story with strong, identifiable characters. This was my first exposure to the Grey Knights, a secret Legion of Adeptus Astartes that has dedicated their lives to rooting out the Neverborn (Chaos) and basically exterminating it. The added element of psyker abilities and the fact that their existence must be kept secret from humans made this a great surprise. Told from the first person view of Hyperion, a young Grey Knight who is part of the Castian group, this story combines the Grey Knights under the instruction of the Inquisition, the battle of Armageddon with the Neverborn, and to make the story really interesting, the Space Wolves Astartes trying to protect humans from extermination by the Inquisition because of their knowledge of the Grey Knights and the forces of Chaos. I was very impressed how the author pulled all this together into a tightly woven tale, full of tension, intrigue, and a lot of emotion as well. ( )

Finding the book was written in the first person was initially a disappointment for me as its not my preferred reading. After the first few pages it became apparent that it did indeed work very well and what followed was an interesting and gripping story from beginning to end.

I liked the slightly different side we saw of the Grey Knights and enjoyed the interaction between them and the Space Wolves.

I was somewhat disappointed though with the cover artwork, instead of a grizzled Space Marine it looks more like a Marvel Superhero better placed on the front of a comic book.

Many readers over on the Black Library site are rating this 5/5. Whilst this book does rate as ONE of the best I've read from the Black Library, its certainly not a book that I would believe should score a perfect 5. I bought early and paid £11 for the ebook version direct from the Black Library and whilst very happy that I did, I would suggest that unless the next book in the Grey Knights series is a must read, then you probably would be better advised to wait a while for the price to drop and pick up another title instead.
