No spoilers 
 Up front it may be important to say that I'm really not a great reviewer and my views on science fiction books may be a bit... different. 
 You can probably guess from my (rare) five-star rating that I really loved the book. The writing itself was great and the portions of the book dedicated to each event were allocated correctly. 
 To me, the best part of the book was the beginning, when Kira was looking for answers about Paragen and herself. For some unexplainable reason, each crumb of information was interesting and exciting to read. The company itself fascinates me and I think about it a lot. What the motivation of the company was (probably money), how they made all these people/products (that's a complicated one), how they were able to protect their monetary interests (strong patent laws), why the government did not just force them to hand over their products (the government must have been run by conservatives at the time). 
 Anyway, I really liked the book, especially the corporate aspects of it. One issue I had with it was the ending (which I will not give away) but most of the book was extremely well-written and interesting. 
 --- A note about the "trailer" 
 For the first book, I watched the "trailer" about a thousand times, fascinated by the product being advertised and the company. This time, I thought it was interesting to have a political advertisement against the rights of Partials. If one were to compare the candidate and his opponent to the political parties today, it would be easy to conclude that the candidate advertising was a liberal. Among other reasons, one thing that really gave it away was the "Not sympathetic, sythathetic" (or something like that). In today's politics, name-calling generally comes from the left. Also, campaigning against individual rights is a leftist thing to do and campaigning against a company such as Paragen is also leftist. 
 The trailer for the second book was different, but not quite as good as the first one.
