Soooo this my favorite book of the entire series by far. 
 This book was so fun to read. All the tricks they played were so awesome to read about. I liked the whole world building and fun teenage atmosphere it held. I really need a hoverboard in my life. Tally was a lot better to deal with in this book and I rooted for her throughout the whole book. I don't know if calling her character strong is a good word, but I appreciate her determination and her smarts. Plus we get introduced to some new characters like Zane who I absolutely love. He is like a better version of Tally and I liked his involvement to the story because he definitely made it much more interesting. Shay was annoying as usual, but I will not even get into that. 
 Scott Westerfeld did not disappoint with this follow-up. The ending took an somewhat unexpected turn. I am dying to see how this story concludes.
