Because this book did made me feel emotions, I would be ok to put the rating up but it was mainly frustration, which isn't all bad so yeah!! 
 ok I feel like I'm not making any sense so I stop soon. 
 I also found the book had some "blurry" parts. I don't know what exactly but I got the feeling. 
 at the end I did like the trilogy, even if I prefered the first book. I think it is still worth to give it a try if you love YA sci-fy.
