After reading some background for Night Lords while researching for my little painting project Here, I got interested in the legend behind the Terror Legion. So picking up my second 40k book every I dove in.
While this isn't a full book review, I'm sure you can some of those easily enough. The book was very enjoyable, if very hero-centric. The two main characters are very well developed, though the rest of the cast seem a little less... dimensioned. The story contains the usual 40k stuff, Imperial paranoia, crazy ruthless Inquisitor, mass poverty, etc.
I feel it gives some pretty good insight to both the Inquisition and also the Lore and background to Night Lords and the slip into chaos.
It also included a lot of Warp-stuff....Like literally, you add the word Warp to the front of a word and it fits in 40k. Warpstuff, warppiss, warpshit, warptentacles, warp-be-damned.
It is a relatively short book, at 190 ish pages, but the story is decently paced, and the descriptions are vivid enough. The end I felt was a little anti-climatic, but left it open for a sequel/interpretation so that isn't too bad.
Overall it is a good read, or a must read if you are a Night Lord fan. If you're not a Night Lord fan, and you get a chance to read this, you'll probably turn into one.
Ave Dominus Nox!
