In this volume, we return to the premise of volume 1, Kyrii walking alone in a mega structure. Now with the goal to find Cibo. This final entry shows us more varied environments in the world, which I was hoping to see more of. 

As always, this book is full of action and some welcomed twist.

The recommendation I give anyone reading is: "the story is a vehicle by which we get to experience the backdrops of the megastructure and the world."

I was thinking that the book was going to end with the revelation that the sphere turns out to be the little girl that we saw Kyrii protecting in chapter 1, giving a sort of "purgatory" feeling to the world of blame; an enless loop. It could be possible that this is still the case (we know time travel existsin this world) but is not confirmed.
