Super immersive, science-y, "hard" science-fiction. The technology, and the jargon and vocabulary, all created a world that I was very interested in and curious about. 
 Part III caught me off-guard, seeming to come out of nowhere. It could have been a stand-alone book on its own, or the beginning of a series of New Earth books. I'd be interested in reading more about this new world and its inhabitants.
