Let me start this review by saying that I absolutely love the three books previous to the shade of the moon. I own all three of them, and I love the writing, the characters, their interactions, and I love how the story wasn't about something going wrong because of mankind; there was a natural disaster, nothing anyone expected to be so bad, and now everyone has to adjust. That being said, after reading the third book, this world we live in, I was pretty sure that was the end to a great trilogy. So when I heard that there was going to be a fourth book, the shade of the moon, I was equal parts excited and nervous. However, other than a few things, this book is really great. Instead of following Miranda, it follows her younger brother, Jon. Jon lives in the entitled area, and I actually real like that Jon isn't the "good guy," and how the book shows us how people will find anything to be prejudice about in others. I never really like Jon, but not because he wasn't well written; I just didn't like him as a person (and I'm sure many will agree with me). Overall, I really liked this book and the flow of everything, but some things felt a little weird. For one thing, the romance between Jon and Sasha. It felt rushed, weird, like they were seeking comfort in each other because they were both outsiders (but in different ways). Another thing that was weird was how everyone just accepted the new social order so quickly, with clavers and grubs and slips. it hasn't been a full generation; it hasn't even been a decade or five years. merely four years have passed since the meteor crashed, and now everyone just accepts the horrible social order. this would have worked if it had been set in the distant future, so that the way they were all so strictly stuck to their ways would make more sense, as those people would have been raised like that. other than that and a other minor things, I felt the book was really good. One thing I will say, though, is how Sasha annoyed me sometimes. I know she was happy to have someone to confide in, someone to talk to, and that she considered him a friend; however, I didn't like how Sasha took it personally that he couldn't talk with her while Lisa's evaluation was coming up. When she would get upset about it, all I could think was, Jon just met you, and the way his character/personality is now, he won't risk Lisa's security (and therefore his own personal security) just for a girl he met a little while ago. I think her heart was in the right place, but sometimes she worried me about things like that. Other than those few things, I really enjoyed the book.
