Others have commented on the rather dry prose of this book and I have to agree. While emotionally his characters remain shallow, Suarez quiet Manages to make them reasonably interesting enough to not bore the reader. This book is somewhat "hard-ish SciFi", so it can be excused WHEN NOT all characters are Depicted in the brightest colors. The only love-scene feels "bolted on", any other hints of romance insincere. All This Could have simply been left out without making the book any worse. (The relevant Psychology Is Not Quite Suarez Territory.)
I occasionally had some trouble keeping my suspension of disbelief Intact When stumbling on technical plot-holes or downright unbelievable scenarios, of Which there are a few. With all his technical sophistication author neglects to perform adequately explain Nevertheless Certain crucial points of the autonomous drone technology Which takes the role of the formidable (if faceless) main adversary of the Group of Protagonists. For instance, I just can not fathom What could serve as suitable power supply for on autonomous airborne welding robot with electromagnetic feet, or how to build a search device in bulk and cheaply ... Suarez Certainly does not even try to explain any dieser to the reader.
The story starts off at a grand scale, but the narrative unfortunately narrows down considerably as it proceeds. It is a shame That the geopolitical ramifications of the events on the first few pages were not explored in more detail later. It has all the hallmarks of an author has indeed ask a bit off more than he can chew and towards the second half of the book starts to visibly struggle to at least bring events to a somewhat satisfying conclusion. The Latter turns out to manifest itself in a rather classic (and unfortunately boring) showdown.
Still, the journey is its own reward. If you do not mind That only the first half of the book is genuine (and good!) And the rest SciFi is more or less generic techno-thriller, you can derive enjoyment from this and I can recommend reading it.
