This is a Horus Heresy book so it takes place 30,000 years in the future not the world of Warhammer 40K.so this establishes and explains some of the mythology for W40K gamers. For me, it was an interesting story but I didn't feel that I 'had' to read this.since I have not connection with the Thousand Sons. If you're a Thousand sons fan or gamer, this is must-read material.

This also really makes you see why you'd support the Thousand Sons. Basically, the Thousand sons use psychic abilities to warn the Emperor of Horus' treachery and in response, the Emperor sends an army after them (that makes no sense and.makes you really wonder what the Emperor is thinking). In the end, I absolutely loved it, but the beginning was so bad I almost quit this book.There's something very consistent about most of these stories regarding chaos space marines: most chaos space marines had a very good reason to hate the emperor. It was also nice to see events we have been hearing about for a long time, like the Council of Niccea, Magnus's big mistake, and the battle on Prospero. After that the story went into high gear and I found myself listening to it in the car, in my living room, and even while I cooked. I was at work and just let the first four hours play in the background. By the end, he was a terrific narrator, he just needed some time to get there. After that I got hooked and the narrator seemed much more confident and invested after this point as well. That being said.The book really picked up after they left that first planet.

The narrator had a hard time differentiating the voices in the first part of the book and the first 3.5 to 4 hours of the story were dull. The beginning hours of this audible were a slog to get through. As with many books in the horus heresy, this book suffers from an excess of fluff.
