As a straight science-fiction the book is a solid four stars, but I give it five because it introduces a novel idea that has parallels in our current society. First, the story. This is the sixth novel in the Cassandra Kresnov series. She is an android/synthetic human/whatever with essentially superhuman strength, reflexes, and computer networking capabilities. This general setup can be boring, but the writer has made the character appealing and has obviously given tremendous thought and planning to this series. There is also a good job at sketching the 'world' the story takes place in and has other interesting characters. The descriptive writing is good and the action sequences engaging. On the negative, there are too many action sequences, Cassandra and her allies skate through so many fights where they kill herds of both human and other synthetics that I found myself starting to speed-read through some of them. A major negative about the writing style of the author is that the view of who is talking/thinking shifts in mid-paragraph such that the reader isn't sure who is being referenced - making the reader stop, go back, and sometimes have to assume who is the speaker. This got definitely annoying. Still, overall a definitely superior piece of work and well worth the read.
What gives the book an extra star is the idea that when humans are networked too much they can tend to be subject to "Compulsive Narrative Syndrome," where when they get most of their information from a single viewpoint, the brain physiologically gets locked into ignoring contradictory information even when presented to the person. I don't know if the author intended to draw current parallels, but I certainly drew it when considering our current media and political situation. All of us likely know people who NEVER watch Foxnews because it's so conservative, and only watch MSNBC - or vice versa. I believe I remember a liberal columnist from the New Times writing how confused she was when Bush II got elected because of the hundreds of people she personally knew, not one had voted for Bush. What was striking was that it never seemed to occur to her that there was ANY other political view except the one she had. Such people sure fit the description of CNS in the book. Same with considering Islamic extremists and suicide bombers - people who have been indoctrinated for so long and so much that they seem irrational - and may well be. In the book, CNS can be untreatable, the victim never able to break out of a physiological/neurological box - a sobering thought for our current world.
