The City of Ember
In the year 241, 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.
The City of Ember is a dystonian book about a city that has survived a horrible event that has left the rest of the world a different place than we know it now. I really liked this book, and the characters. It was a fun read.
