This book starts off after the two main characters in The City of Ember escaped Ember and got to the surface. I really liked this book because it had new and original characters that were really easy to like/dislike. This book also has drama and from what the back of the book spoke about, "the war". This book is full of drama, action, and adventure and I really liked it. I would definitely recommend this for someone that likes those types of things, or if you read the first book.
