Angron is my favorite primarch in warhammer, so rather unsurprisingly i enjoyed this novel. That said, only about half of the book follows Angron, and its a psyker looking at his memories while in a coma. The other half of the novel is about a centurion trying to prevent the implementation of the butchers nails, its a fine story thread, nothing to write home about. The parts following Angron though, I really enjoy. We get a pretty comprehensive detailing of Angrons life before the Emperor stole him from his fate. In particular near the end of the book, outside of the coma, we get to see a conversation between Kharn and Angron, and its easily the best part of the book. Overall, if you like Angron as tragic character he is, I think you’ll like the book. Its not as good as Betrayer, but it is a good short read.
