A great book with a unique hook into the 1980's and early computer gaming, movies and culture. If you saw the movie you need to realize it is only about 20% of the detail and quality of the book. So much more in the book that they obviously just could not fit into the movie and/or could not get license to use in the movie. The book just has so much more detail and plot. Well worth the read. Also got me to reach the authors other book ARMADA which is just as good.
