The follow-up to Red Rising, this one really ratchets things up as Darrow continues his studies of the art of war under Augustus all the while wondering what his role in the Sons of Ares revolution still is. I really enjoyed how Brown further developed key characters and presented them in a very intriguing political environment. Darrow spends the whole novel conflicted as he tries to balance his Red/Gold status and his duties to the revolution with his ambitions to Augustus overthrowing the solar system rule of Octavius of Lune.
The book flows very well and I really am impressed with how Brown has taken the "Hunger Games In Space" theme and really expanded on it. No spoilers here, but the ending was a total surprise. On to the next one to see where this ends up.
