Story enriched and entangled comparing the previous books. Sometimes I have a feeling like playing a game (old piece Legend of Dragoon came in mind) while listening to Cradle books. Similar with some anime like Fairytail. The bureaucracy and mathematical style duty heavenly beings are odd, but satisfying style too (reminds me of robotic city in above mentioned game) . It makes it a bit scifi. Plus magical prosthetic arm and parasites. .. Cradle have it all. Fighting scenes improved greatly too.
