I am not a science fiction reader but I picked this one up in my local library and thought it looked interesting. The heroine is watching "the Grid" and reporting back to her bosses the Machine Front. The Grid is perhaps overlaying the Earth, perhaps another planet, perhaps imaginary/virtual reality? It seems to be intelligent but is it malevolent or just a victim of the humans who would "rape" it's treasures? What takes place there is real -- or is it? Could it be all an advertising man's fantasy where it becomes possible to accurately predict what will be successful. Messages about alternative realities abound -- is the arcane world of karate any more real? Is it really more honourable than the world of the masses, or is our heroine safer in prison with armed robbers and the like?
Having finished the book I am not sure I am any wiser but I certainly enjoyed the time spent with this book and feel sure it is one that will remain with me for a long time to come, it is certainly different and thought invoking.
