I wasn't sure how much I'd enjoy this book, but I gave the author the benefit of the doubt, based on the strength of "The First Heretic". I was not disappointed; this was a fantastic read, and provided a much deeper, broader context for the actions of a heretical legion, just as in First Heretic. I strongly recommend it, and I will be purchasing the sequel as soon as I'm done with this review!

Great read. The night lords are fast becoming one of my favorite chapters. Their treachery against the empire has to do with the way that the emperor treated their primarch and they very begrudgingly sided with the forces of Chaos.
