City of Ember

I am almost done reading The City of Ember by Jeanne DuPrau. Today the 5th grade class went to see the movie. In the city of Ember, twelve-year-old Lina trades jobs on Assignment Day to be a Messenger to run to new places in her decaying but beloved city, perhaps even to glimpse Unknown Regions. It is the first book in the Books of Ember series. The series has 4 books so far: The city of Ember, The People of Sparks, The Prophet of Yonwood, and The Diamond of Darkhold.
