The story goes as follows: Jack, a computer programmer who worked on grouped processing is out of a job. His wife Julia has an executive position with a company that is using Jack's programs to develop nanotechnology spy tools for the government. The technology comes to life, goes berserk, and Jack is called in to figure it out because he understands the program. With a few interesting but highly implausible twists (as if the whole thing isn't somewhat implausible) Jack ends up saving the day, but in doing so kills his wife who has in part caused the mess.
I enjoy reading Michael Crichton novels because he usually teaches you something about science. What I find more interesting about Crichton is that he seems stuck on certain notions, namely Chaos Theory. Perhaps it is true that nature is uncontrollable (to a degree at least) and that, try as we might, we cannot predict what life will do, but how many times can you use this as a plot device? This was the entire story to Jurassic Park I, and II, and III. He does make an interesting point about psychology and how individuals may be very insightful of the problems facing other people but are usually pretty bad at understanding their own psychological problems. Overall the book was interesting to read but not my favorite Crichton novel.
