I'll give you a bit of a warning right now. I'm going to discuss a bit of the plot of `Daemon'. If you haven't read that book, then you may want to hesitate before reading this review. If you simply want to know whether I enjoyed this book & if you should purchase this, then the answer is yes. I loved this book & you absolutely have to buy it. However I will warn you- the very basic outline of `Freedom (tm)' will give spoilers on the ending of `Daemon'. You've been warned, so on with the review. 
 In `Daemon', we were introduced to genius computer mogul Matthew Sobol or rather, to his computer generated avatar. We learned that he had unleashed a computer creation that threatened to overthrow society. A few select individuals knew about this, some of them working for the daemon, some against it. Some of those individuals were wrongly accused of creating the daemon, with one of them- Pete Sebeck, being executed for it. Now we get to learn exactly what Sobol's long term plans were as Sebeck (resuscitated at the end of `Daemon') is commanded to do a seemingly impossible task: to justify the freedom of humanity or risk being under the control of the daemon forever. 
 Meanwhile the hyper intelligent hacker Gragg (now known as Loki Stormbringer) is on a hunt for the Major. Even as he continues his hunt, he alienates himself from the rest of the darknet community & runs the risk of doing the daemon project more harm than good. The roguish Jon Ross is still on the run & his would be paramour Natalie Phillips is torn between joining him or staying with her government... even as it begins to fall around her. 
 I absolutely loved this book on two different levels. On one level you have the sheer enjoyment of a techno/sci-fi thriller. You can't beat the energy in this book- it's incredibly fun to read. On the other level, you have a story with a hidden allegory. It makes you question whether change would show up as good or bad. At one point of the book, a character equates the daemon's change with the settlers inhabiting the United States, saying that at the time, the change was not good for everyone but turned into something big. 
 The narrative continues to jump from person to person, which at times made me a little frustrated because I wanted to stay with one specific person to see where they were going. I'll admit it- I had favorites amongst the characters, (mostly Sebeck & the sociopathic Loki) which is pretty much the only reason I'd gripe about the shift in perspectives. People who complained about the unrealistic technology in the first book should be warned that it doesn't change in this volume. (Hence the reason I use the term "sci-fi" when describing what type of book this is.) You see more of it in this book, with new add-ons that I won't describe here, mostly for spoiler reasons. 
 I read through this book pretty quickly during the Thanksgiving break, mostly because after the cliffhanger in the previous book, I just REALLY wanted to know what happened next. I will admit that while I enjoyed this book immensely, the ending was a little weak. There is the potential for another book if Suarez wants to write one, although if not, there's enough of an ending to satisfy me. If he does write one, I can say that I will read it. I really liked the imagery as well as the implications of several key characters at the end of the book. (I can't go into detail, but it's safe to say that they ended up as larger than life characters.) 
 Fans of the previous book will enjoy this book. If you didn't like it, then you may want to skip it- it's more of the same. And if you haven't read the previous book then I recommend skipping this book until you've finished `Daemon'- otherwise you will be terribly lost plot-wise.
