I really had hard time rating this book.
The futuristic set is really interresting. The characters are likeable but following Chaz's mind was like taking a tour in a rollercoaster. Most of the time, I enjoy it. But at some point I couldn't understand his reactions: when too much things have already happened and he still can't made up his mind, he was getting on my nerves. It may be harsh, but I couldn't feel for him anymore.
The writing got hooked and overall I liked the romance.
I got a big issue with one thing: how can they have a perfect connection if it is forced and painful? (those who have already read it may understand what I'm talking about.)
For me, it's a real 3.5 stars.
