I thought this book was pretty good. I love dystopian society books, love science fiction, especially when romance is thrown in there. However, this book was clearly a set up for the next (and the third in the trilogy), so in my mind it was missing a bit, which is why I could not give it 5 stars. I totally feel for Xander in this, and I hope his future is bright, as well as for Cassia and Ky and their story. I wonder how long I will have to wait until the 2nd book is released.
