I started reading this book, thinking that it would be just another sci-fi/robot book. Man, was I wrong. From the beginning, this book had me hooked. The love story between Rachel and Jonathon was sweet. It had just enough violence...which was explained at the end. Speaking of the ending, it was such a complete and utter surprise that I just sat there for a minute with my mouth open and was thinking to myself "Well now, that makes sense". I highly reccomend reading it!
