Ok, I don't want to say anything negative about this book, so I will only say that the story wasn't the most exciting. To me, this was not a page-turner. This book is excellent when it comes to wanting to read a story about what the "real world" might be like after a disaster.
I have students who LOVE this book and defend it to the very end. So I can only say that this is one of those iffy books that it's popularity depends on what the reader likes.
