I just finished reading this and I really enjoyed it. the story doesn't cover much of the Space Wolves razing of prospero. Rather it covers all of the events leading up to it. I thought that Abnett found a really interesting way to follow this story and even has a pretty good twist in there. Basically it follows Hawser, a human from Terra (earth) who is more of a scholar/academic than a soldier, who finds himself working as a sort of journalist/storyteller for the most feared legion of space marines known as space wolves.
