CIP: "Having escaped to the Unknown Regions, Lina and others seek help from the village people of Sparks."
Duprau's second novel picks up right where The City of Ember left off but also gives enough background to the story that those who picked up the series at Sparks will not be left in the dark. The story explores conflict, dishonesty, and resolution in the same fast-paced style as the first book of the series. Recommended for readers aged 9 through 14.
Favorable reviews from Booklist ("a satisfying follow-up to the first book")and SLJ ("a good choice for even reluctant readers").
