This book had a plot that surprised me as well as scared the crap out of me. Something like this could happen in the future with the advancing technology of computers. It is kind of like machines could be smarter than people. If that happens I think we would become useless in this old world. Anyway, I really enjoyed this book except at the end I think the author could have closed up a few ends a little better. If you read it, and this is your type of genre' I am sure you will enjoy it too!
