If I were to use one word to describe this book, it would be: Meh. 
 On the plus side, this second book in the trilogy gave us insight into Ky's character. It did add a different perspective, and filled us in on missing pieces of the first book's story. The down side to this is that I had a hard time distinguishing between the two characters. Their voices were identical. I would be reading a chapter, and realize halfway through that I was visualizing it wrong. Very frustrating! 
 I also, hard to believe considering I'm getting both sides of the "romance", found the relationship between Ky and Cassia to be...well... limp. I didn't get the impression that they were great loves, even when I was told that they were. I found it unbelievable the lengths to which these two "lovers" would go to be with each other. 
 Try as I might, I just couldn't get into it. Perhaps it was simply that too much time had passed since I read Matched, and I had forgotten the characters. Even as I read Crossed, I couldn't remember anything about the first book, the characters or the plot. 
 I'll still give the third book a shot, but I have to presume that I will have forgotten this book too, by the time it is released.
