This book starts with an interesting premise, but the setting ends up deteriorating into a too-predictable, disappointing resolution. Less fundamentally, there are massive plot holes that render the main (well, only - there are no side tracks) storyline partly nonsensical. 
 The author focusses exclusively on his vision of the society and technology underpinning the story, bits of which, he goes to great lengths to explain in quite unimportant detail - though only bits that have currently-understood explanations, there's very little technobabble. Unfortunately, this leaves no character development whatsoever, the reader does not get to know even Arik, the protagonist, much less any of the supporting cast, who remain only names without face, without opinions, without attitudes, without any characteristics. 
 This is a matter of taste, and I wouldn't have minded if it had been supported by better writing: I first heard the phrase "show, don't tell" from C.E. Murphy. Advice that Mr. Cantrell seems to have never received. 
 What description there is of characters is awkward - "Kelley had the air of a used car salesman sometimes, but he also had an authentic and vulnerable side to him that even his detractors admired". 
 Vast swathes of the book consist of this sort of narrative exposition with great pathos, from the brief - "Arik thought about how he was taking risks far beyond anything he had ever imagined. He couldn't tell anymore how far he was willing to go, or even what he might be capable of." - to the long-winded:

 When the maglev stopped in front of the Wrench Pod, Cam and Zaire were standing on the platform. Arik knew that things would be awkward between he and Cam, but as he watched them step into the last section and seat themselves opposite himself and Cadie, it occurred to him that things could also be very awkward between Cadie and Zaire. He wondered how much Zaire knew about the baby. Had she encouraged Cam to do what he did, or was it possible that she didn't even know that the baby had once been her husband's? How would her feelings toward Cadie affect her feelings toward Arik, and how would all their emotions influence their ability to listen objectively to what Arik had to tell them? 
 Arik realized that the moving parts that drove human emotion and interaction were far more intricate and delicate and explosive than anything found inside manmade machinery. He knew that in order to change all of their lives, he needed to tear down everything that had been built up between tem, compact it all down into a clean and solid foundation on top of which he could start building something completely new, something with no moving parts, something so towering and imposing that none of them could dismiss it.

 -- after "husband's", everything else just gets in the way. There's a lot of that. 
 The premise of the book is interesting, and the storyline had a chance to be gripping, but reading through this was more of a chore than a pleasure.
