Query: This is an interesting but good book

To me, This is a really good book with good description. The only problem i have with this book is that the kids are too young. I think that 9-year-old's would not be thinking like how the author made the kids act, think and behave. It would have made more sense if they were a couple years older. But overall, I loved this book and i think every kid from age 12-25 should read this.
