The final book in the Ember trilogy, which nicely wraps up the series. We got the feeling that the author was intentionally trying to wrap up the series, as some of the content was a little "final" when it perhaps didn't really need to be so. Nonetheless, the closure was appreciated by our 7 year old daughter, who would have been asking for the next book in the series if it hadn't so clearly finished. I was personally a little disappointed about the final nature of the green star, as I would have preferred for that particular topic to have been left out of the "Ember" universe, and for the star, perhaps, to have been something to do with the main plot of the novel, or even just left out altogether. But it doesn't detract from the main story, which is quite a bit faster paced than the previous two, so you'll need to pay attention. The book contained some good themes about convictions, believing in one-self, and loyalty, as well as a strong element of forgiveness, all of which are useful for children. There was a good opportunity for tackling bullying which was missed, but which can be drawn out if desired easily. The narrator was new, with a clearer accent for non-US listeners, which was appreciated.
