I really loved this book. I cou;dn't put it down! I used to think it would be super cool if all the adults just disappeared, but now I would prefer they stay here. The book, in my opinion, had some very real circumstances. Like the bullies and tough people taking over. I think that could happen. I also think people would start turning against each other. So that was real for me.I also like the whole mystery about how a kid could make a wall the way he did. So i can't wait to read the next one!
