I did not read this book to anylize, but for a school assignment with pressing deadlines. I am sure that if I read it to critisize, I would have thouroghly enjoyed doing that.
But for pure pleasure/booktalk, this is a fifty-fifty book. About half the people who read it will like it and about half won't.
If you are the kind of person who is bored over survival stories where the author tries to keep you interested with emotional thoughts and descriptions (but doesn't do a very good job) about (yet again) children alone, than this is not the book for you. On the other hand, if you like books about children who have never lived in the outside world and are searching for their parents or parent, than this, I am sure, is a book you will like.
But, I still must say (despite the fact that I did not, overall, like this book) it had a very touching ending.
