The City of Ember Books in Order

The City of Ember books are middle-grade science-fiction adventures about what happens when a community loses touch with its past. The first story begins in Ember, a city built far underground as a refuge for people after a long-ago disaster. Its citizens know no sun, moon, or stars. Their world is lit by electric lamps, and nearly everything they need comes from storerooms, gardens, pipes, and machines that few people fully understand.

But Ember is failing. Food is becoming scarce, blackouts are more frequent, and the city’s leaders offer little help. Twelve-year-olds Lina Mayfleet and Doon Harrow begin at different ends of the city’s daily life, but a damaged message from the past brings them together. They have to figure out what the fragments mean while deciding whom they can trust and whether anyone will listen to two children.

The pressure is immediate: if the lights fail, Ember may not survive.

The People of Sparks picks up after the escape from Ember. Lina, Doon, and the other Emberites reach an aboveground settlement called Sparks, where they encounter sunlight, open sky, plants, and people who have lived very differently. Safety is not the same as peace, though. The newcomers need food and shelter, while the people of Sparks worry about what sharing their limited resources will cost. The conflict becomes less about puzzles and more about fear, scarcity, and whether two groups can choose restraint over retaliation.

The series then steps back with The Prophet of Yonwood. It is a prequel set long before Ember, in a town gripped by a frightening prophecy and growing suspicion. The book follows Nickie, a girl who has recently moved to Yonwood, as she tries to make sense of adults who believe they are protecting the world. It adds context to the larger history without requiring readers to know every answer in advance.

Finally, The Diamond of Darkhold returns to Lina and Doon. Their people are facing their first hard winter aboveground when evidence of a lost device sends the pair back toward the abandoned city. It brings the series back to its strongest ingredients: a risky journey, a forgotten piece of knowledge, and two young people trying to use what they find for the good of others.

These books are tense but accessible. They are full of dark tunnels, old instructions, failing systems, and narrow escapes, yet the real thread is cooperation. Lina and Doon are brave, but they also make mistakes, argue, and keep learning. Readers who like mysteries, survival stories, and imagined worlds with practical details will find a clear reading path here: start with The City of Ember and continue in publication order.
