An early example of Neal Stephenson's work, this does not have quite the depth of imagination of later offerings (such as Snow Crash or The Diamond Age) but the action is fast, the use of language excellent and the science spot on. In most works of Science Fiction the science is Physics, yet in Zodiac it's Chemistry and Biology that get a chance to shine. The introduction of a character with some scientific training into a situation where those with more knee-jerk views often dominate is a pleasing feature of this novel. The plotting sometimes goes slightly astray (the Satanist Rock band's involvement is sketchy and ill explained) and our main protagonist certainly seems to be more a super-hero of the 50's who can do no wrong than a late 80's drop-out. However these minor points should not detract from this books appeal as a a good action read. I would like to know if it has inspired anyone to partake in some direct action?
