The City of Ember - by Jeanne DuPrau

Lina and Doon are just two normal 12-year-olds in the city of Ember, except for one little thing... they're not satisfied. They're not willing to sit around while their entire world fades into darkness, and they are both sure that there is more out THERE, beyond where citizens are allowed to travel, beyond the city that is all anyone has ever known or ever dreams to know. It's up to these two brave and adventurous children to set off on the quest that will quite possibly save the city of Ember from extinction. But what do they find? Sorry, you've got to read to find out.

This futuristic book brings the reader right into a strange civilization that is much different than our own, but with the same type of human relationships. Can two children get away with questioning the government and trying to change the way everyone thinks about everything? Some of the book is hard to follow, making it ideal for experienced readers, the plot twists and turns enough to satisfy mystery lovers, and the drama will keep adventure fans on the edge of their seats. Best of all is what the two discover when they dare to go beyond... There are two more books in the series, so when you get to the end, you're all set to keep going.
