Content warning Vague references to character motivations
Finished! It's a a real thrill ride, maybe my favorite of the Heresy series so far.
I have to say though, I'm a little disappointed. Horus' betrayal seemed to come out of nowhere in the last book, and it's even more confusing here. Why would so many Space Marines join him? How did they spread this message enough for people to join, but not so far that it didn't get discovered early?
