This book is full of choices, lies and hover boards, that will keep you eternally gripped in it's hold. I finished this book in one day since it was so good. I thought the cliffhanger was great, good idea Scot, great way to earn more money, you just need to know what happens.
I disliked the part where Tally volunteers to become pretty, after all that we learned about the consequences of becoming pretty. I thought that was pretty stupid (in Tally's case, not the authors, in that it was clever). I loved Shay quite a bit, but I hated it when she became pretty, and when in the Pretties book how she becomes special. She goes out of line my friends, out of line. I hope she she see the truth someday.
I recommend this book for 12+. Hopefully it will draw in more ever starving prey, like it did for me.
