4.5 Stars... 
 All right I was not sure what to expect with this as I've never read a cyborg book before. I loved the dynamics of the characters and how they worked. Joan was a diverse well rounded character, she was strong and yet giving. I liked that she used her background in her approach to Rage and that she didn't discard the abuse he went through. She addressed it and tried to help him. She even refused to tell him about her trials as they would distract him. She never pushed and advantage even though she could have. 
 Rage, he was an alpha. Nothing her went through changed that about him. while he was suspicious of Joan at first he is also drawn to her. I thought it intriguing the way he justified to himself that he was growing to care for her. It fit with his character. A cyborg like him would never jump straight into a trusting relationship and Ms. Sax conveyed that.I liked that it wasn't instant love, that time progressed between them. 
 Now I know people were upset about the assault scene...It was bad if you cant handle violence against women, in your plot this book is not for you. This moment was actually the only reason its not a 5 star for me. I understand that she needed to be healed and that the most efficient way to heal her was how he did it and that he was tortured by it....Still hard for me to swallow. I was grateful that Joan didn't remember; but she would need some recovery time emotionally, so it detracted from the story... Showing he emotional journey would have rounded it out instead of trying to quickly process a traumatic event. 
 I loved the plot twist at the end and that Joan changed the way the Cyborgs viewed all humans. I loved the interactions of the characters and I will be continuing this storyline. I ended up going back and rereading it as soon as I was done because of the emotions between Rage and Joan.
