But is it already too late to avoid a devastating war?

Good book but I didn't like this one as much as 3 other Ember books.

I took the whole book series at a meet-up. I'm sure I've seen a movie based on these.

I didn't get into this book at all, though I liked the other City of Ember books very much. This was too far from the world of the other books in the series and there was too much talk about god, so I gave up.
I'll probably release or give this book to someone as a package with the rest of the series.
This book is part 4, btw, not 3 as it says in the title in this profile.

On the book swap shelf near library cafe.
