The book was very entertaining, I'll give you that but there were quite a few things that bothered me.
First, Sonny was very manipulative in her friendship with Amy and I was surprised she got away with it for so long. I was happy that it caught up with her and she had to deal with all consequences in the end of the book. I wish we could have seen even more character development.
Secondly, Skyler was an odd character. He was a one person in real life and an entirely different person online. He was a very condratictory character and Sonny definitely put him on a piedestal.
Thirdly, Wes and the Rush family seemed so different from when we read about them in the DUFF. I was confused. I didn't remember them like that at all (with the exeption of Amy). I wish we could have gotten more than just a glimpse into their lives and what had changed since the DUFF. It confused me and I didn't enjoy reading about them as much I hoped because they seemed to be entirely different characters.
