The City of Ember by Jeanne DuPrau is a novel about Lina and Doon, twelve-year-olds living in a city called Ember, a place that is lit by large lights all over the city. Ember seems to have fallen on some hard times, however, and blackouts are becoming more and more frequent. When this happens, pure blackness swallows all of Ember. No one has ever left Ember as the unknown regions are also full of complete darkness. Doon suspects that he might be able to help the city of Ember, and begins to search the generator that runs all of Ember's electricity. As times seem to be getting worse, Lina discovers a clue that might help them escape. Lina and Doon must work together in order to figure out how to save Ember before it's too late. Read this book if you like mysteries, if you're interested in novels that take place in a strange future, or if you enjoy book series. I give it an 8 out of 10.
