Descent of Angels, Book Review

I Really enjoyed this book, its not hard core Boltgun action. Its a deep dive into the Dark Angels and their history through the eyes of two initiates.
The lion is seen from a distant and he slowly becomes bigger part into the story. If you want to learn more about Dark Angels you'll really like it if you pick it up as you work your way through the Horus Heresy you'll just like it.
