This novel sees a growth in the world. I would say this novel probably does the most world building, as well as the novel prior to it, than any novel that came before. At the time of writing this, I have finished the finale to the series, where many of the threads started in this novel are wrapped up! Which is exciting, my favorite characters and plot threads reside in what happens in this novel.
I will say, the pacing is a tad slower in this volume than in the previous 8. The writer seems to be taking more care to flesh things out and add detail and reality to his world. Which is fine, it just takes a bit more dedication to read. For me, previous volumes seemed to flow, where pages would turn on their own accord. This has that, just not to the prolific extent I was used to.
The set up that happens in this novel eventually turns into the finale for this Saga, which I will tell anybody, is perfect in nearly every way.
If you are still reading this review I am ashamed of you. Get reading. There is a finale you need to get to and your still two books away from it. The finale is perfect in almost every way. Its worth plowing through any slowness to get there.
