Anticipating The City of Ember

This is the second book of the course that I have not read. I know that it is the first book in a series and was made into a movie a few years ago. By brother and sister both read the book, and my sister may have actually read more of the series. I did see the movie on a plane one time. I remember being skeptical of the movie but actually enjoying it a little. However, knowing the state of Hollywood and their reputation for correctly interpreting books into movie, I'm assuming that the book is not like the movie. But consequently I know the story line and know that it follows a girl in a dying dystopian world. I am curious to see how this novel relates to the other dystopian stories we have read.
