The City of Ember

As the book starts off, a coalition of architects, scientists, and doctors known as "The Builders" have built Ember, an isolated, underground city with enough supplies for its inhabitants to survive at least 200 years. The goal is to keep humanity safe from an impending apocalyptic disaster. They handed the first mayor of the city a locked box holding instructions for the city's inhabitants on how to leave Ember when the time comes, to be passed down from one mayor to the next. After roughly 200 years, the timer on the lock will expire and the box will open to reveal the instructions inside. The box is passed successfully from mayor to mayor, until the seventh mayor who, thinking the box might contain a cure for his deadly cough, takes the box home and tries multiple times to break it open, but fails. He then dies before he can return the box to its rightful place or inform the next mayor of its importance.

Approximately two hundred and forty-one years after Ember is established, the city′s supplies are in danger of exhaustion and its hydroelectric generator is in decay, causing the power to go out intermittently. At their graduation ceremony, young people are assigned jobs by lottery: Lina Mayfleet is assigned the job of "Pipeworks Laborer" and Doon Harrow is given the job of "Messenger". However, both are displeased with their assigned jobs so they exchange their assignments and begin work in their respective positions. It is revealed that the seventh mayor was Lina's great-great grandfather and the box with the timed lock is in the closet in their house. By now the timer has finished counting down and the lock has clicked opened. When searching the closet, Lina's grandmother finds the box but tosses it aside, not realizing its importance. The opened box is found by Lina's baby sister, Poppy. When Lina comes home, she finds Poppy with torn pieces of paper in her hands and mouth, Poppy has all but destroyed the instructions. Lina saves the scraps of paper, thinking they must be an important message from the Builders of the city, since the message is typed and no one in Ember can write like that. The writing on the message resembles the writing on labels and books left by the builders in the city. Using some glue, Lina reassembles the message as best she can. There are many gaps and some words make no sense like "boat" since no one in Ember has seen or heard of boats. Thanks to side character Clary, friend of Lina’s father, she discovers that the title of the document is "Instructions for Egress" or instructions for exit. Lina realizes that the document is instructions on how to leave their dying city. One of the words on the instructions is clearly "Pipeworks", so Lina enlists the help of Doon who is now working at the Pipeworks. The Pipeworks are underneath the city and a large and fast underground river runs through it that provides the hydroelectric power that Ember runs on. After much trial and error, she and Doon decipher the instructions from the builders. The instructions lead to a hidden room built on the side of the river that contains hundreds of boats as well as matches and candles to create portable light, something unknown in the city of Ember. The builders meant for the citizens of Ember to board these boats and be carried down the river into the outside world.

Lina's grandmother dies shortly after their discovery, and Lina and Poppy move in with a neighbor, Mrs. Murdo. At work, Doon discovers that the mayor of Ember and a storeroom worker named Looper have been stealing supplies, and he and Lina report the crime to the guards, who unknown to them are also corrupt. Upon following the instructions given in the note, they find the room with boats and candles meant for use in the exodus. On their return to Ember, they learn that the mayor has declared them criminals and there are notices everywhere with their names. Doon and Lina plan to escape Ember in the boats and agree to meet at the Pipeworks at a certain time, but just before, Lina is arrested and taken to the mayor, who plans to throw her in jail. Suddenly, a blackout occurs and allows her to escape without being seen; she meets Doon at the Pipeworks with her sister Poppy in tow. Lina, Doon, and Poppy escape in a boat through the river, its current carrying them forward. When the boat stops, they learn the origin of Ember from a diary left by one of its original colonists. Shortly after they are faced with a very steep climb and emerge onto the surface where they see their city from above and realize for the first time that Ember is underground. They throw a rock with instructions tied to it down to the city in hope that the people of Ember will escape. The novel ends with Mrs. Murdo finding the message on the street.

The City of Ember was praised for its setting and main characters, Lina Mayfleet and Doon Harrow. Kirkus Reviews praised the characters, stating: "The likable protagonists are not only courageous but also believably flawed by human pride, their weaknesses often complementing each other in interesting ways."[3] Sally Estes from Booklist commented how readers would be able to connect to Lina and Doon's courage amidst the conflicts.[4] Robert Sutton from Horn Book Magazine compared the novel to Gathering Blue by Lois Lowry, noting how "the darkness of Ember is essentially literal" with the generator (the mechanical light operator) failing and running out of power, leading to frequent blackouts. Sutton noted how DuPrau does not explain the history of Ember all at once, which would confuse and overwhelm the reader and instead, "allows the events of the story to convey the necessary information". Lina and Doon were described as "good sorts" that are "deeply etched".[5] Dian Roback from Publishers Weekly also praised the "full blooded characters" as every bit as good as the plot which would hook readers until the end.[6] Although Jones Johns from School Library Journal wrote that the setting was not as ingenious as the ones in Joan Aiken's Is and Lois Lowry's The Giver, he said that the characters and pace of the plot would keep readers hooked.[7]

A film adaptation of the novel, directed by Gil Kenan, was produced by Walden Media and Playtone with Bill Murray as the mayor, Saoirse Ronan as Lina, and Harry Treadaway as Doon.[8] Filming was finished in October 2007, and the film was released in theaters a year later on October 10, 2008. City of Ember was released on DVD on January 20, 2009. The film received mixed reviews, with a Metacritic rating of 58/100, indicating "mixed or average reviews".[9]
