I'm sorry, I'm not capable of anything coherent right now, I just loved it! I love these characters so much, everyone is so different and their relationships are so realistic. Alexandra Bracken knows how to write amazing characters. 
 The beginning was a little slow, but I personally don't think it was a bad thing. I enjoyed the build-up and how all the planning and smaller operations were described in detail. This also gave so much time for learning more and more about the characters. (view spoiler)[And some drama. I love Ruby and Liam, and it was frustrating to see them fighting. Finally they talked about everything and after that everything was fine, yay! See Ruby, Zu told you so. (hide spoiler)] I freaking love the gang; Ruby, Liam, Zu, Chubs and Vida! 
 Points for this being one of the few dystopian books/series where the whole world minus America isin't destroyed! As a non-American person it's good to know! :D
