The Outcast Dead (Horus Heresy Book 17) Review

I'm trying to catch up with my Horus Heresy Review series, but right now my reading is outpacing my analyses. The next in the series is The Outcast Dead by Graham McNeill. This is one that I'd heard whispers about, so was excited to read it. I was not disappointed in that the book shows a lot of Terra and the Imperial Palace in particular, not to mention insight into the Astropaths, a pretty underrepresented group. Anyway, as always, spoiler alert ahead.
