"The City of Ember"
The first book in the series introduces Ember, a strange city lit by electric lights. No light comes from the sky, because there is no sky above Ember.

"The Books of Ember" are the best science fiction novels I have ever read. As a collection they are simply amazing. Not only does Jeanne Duprau teach important lessons, but she also provides fascinating and exciting plots that will keep any reader satisfied. I highly recommend that you read each "Book of Ember."
