(My review from Goodreads)
I liked the beginning and loved how the story was developing until a certain point; however, I was expecting an epic finale, some huge resolution at the end but it never happened. I think this is due, in part, to the many details and subplots presented brilliantly and evenly throughout the book. It did get a little confusing at times and everything unclear was clarified quickly afterwards; it might have been better if some of the clarifications were saved for the very last chapter.
I liked the writing style ("I am so sorry, Puzzled Reader" was totally heartwarming ;)) and some of the scientific/technical concepts (the UL-6 security was ingenious; would have liked to know a little more about the Vita).
The reason I'm not giving the book full four of five stars is that I don't think that it will, so to say, leave a mark. I'm not going to think about it for weeks after I've read it thinking "Wow! That was a brilliant story!". I would recommend it to friends as a nice, well-written read, but not as a masterpiece.
Finally, I'm happy that I managed to get the book for free (before March 8th) but it would have totally been worth it to buy it too. Good science fiction should be encouraged!
