Less claustrophobic and more ambitious than its predecessor, "The People of Sparks" is a deftly constructed fable, its message universal and sensitively rendered. -- The San Francisco Chronicle
Occasionally I was reminded a little too strongly that this is a children's Book -- Sondra Eklund, SonderBooks
The first Book, The City of Ember, was a fun but unexceptional story -- city underground is failing, children have to find a way out before it's too late. This sequel, on the other hand, goes in a different direction -- less action, more thought-provoking. -- Matt Berman, Common Sense Media
