** spoiler alert ** 
 The premise to the The City of Ember is similar to my beloved Wool series. A group of people live underground, set up there by a group of their predecessors, as a way of continuing the human race after the destruction of the earth. Like in Wool, the inhabitants are unaware of the outside world, the history of the human race, or the existence of anything outside their small city. 
 The City of Ember is a fun and quick read, looking forward to reading the rest of the series.
