USA Today "DuPrau's first foray into fiction creates a realistic post-apocalyptic world. Reminiscent of Robert O'Brien's Z for Zachariah, DuPrau's book leaves Doon and Lina on the verge of the undiscovered country and readers wanting more."

Starred review from March 10, 2003
In her electric debut, DuPrau imagines a post-apocalyptic underground world where resources are running out. The city of Ember, "the only light in the dark world," began as a survival experiment created by the "Builders" who wanted their children to "grow up with no knowledge of a world outside, so that they feel no sorrow for what they have lost." An opening prologue describes the Builders' intentions—that Ember's citizens leave the city after 220 years. They tuck "The Instructions" to a way out within a locked box programmed to open at the right time. But the box has gone astray. The story opens on Assignment Day in the year 241, when 12-year-olds Lina Mayfleet and Doon Harrow draw lots for their jobs from the mayor's bag. Lina gets "pipeworks laborer," a job that Doon wants, while Doon draws "messenger," the job that Lina covets, and they trade. Through their perspectives, DuPrau reveals the fascinating details of this subterranean community: as Doon repairs leaks deep down among the Pipeworks, he also learns just how dire the situation is with their malfunctioning generator. Meanwhile, the messages Lina carries point to other sorts of subterfuge. Together, the pair become detectives in search of the truth—part of which may be buried in some strange words that were hidden in Lina's grandmother's closet. Thanks to full-blooded characters every bit as compelling as the plot, Lina and Doon's search parallels the universal adolescent quest for answers. Readers will sit on the edge of their seats as each new truth comes to light. Ages 10-13.

Gr 4-7-DuPrau debuts with a promisingly competent variation on the tried-and-true "isolated city" theme. More than 200 years after an unspecified holocaust, the residents of Ember have lost all knowledge of anything beyond the area illuminated by the floodlamps on their buildings. The anxiety level is high and rising, for despite relentless recycling, food and other supplies are running low, and the power failures that plunge the town into impenetrable darkness are becoming longer and more frequent. Then Lina, a young foot messenger, discovers a damaged document from the mysterious Builders that hints at a way out. She and Doon, a classmate, piece together enough of the fragmentary directions to find a cave filled with boats near the river that runs beneath Ember, but their rush to announce their discovery almost ends in disaster when the two fall afoul of the corrupt Mayor and his cronies. Lina and Doon escape in a boat, and after a scary journey emerge into an Edenlike wilderness to witness their first sunrise-for Ember, as it turns out, has been built in an immense cavern. Still intent on saving their people, the two find their way back underground at the end, opening the door for sequels. The setting may not be so ingeniously envisioned as those of, say, Joan Aiken's Is Underground (Turtleback, 1995) and Lois Lowry's The Giver (Houghton, 1993), but the quick pace and the uncomplicated characters and situations will keep voracious fans of the genre engaged.-John Peters, New York Public Library

The city of Ember has no natural light, and the blackouts of its antiquated electrical grid are coming more and more frequently: "disaster was right around the corner." So thinks Doon, a curious twelve-year-old who, along with his spirited schoolmate Lina, determines to save the city. The writing is agreeably spare and remarkably suspenseful; fans will be pleased to know that there's plenty of room for a sequel.

Gr. 5-7. Ember, a 241-year-old, ruined domed city surrounded by a dark unknown, was built to ensure that humans would continue to exist on Earth, and the instructions for getting out have been lost and forgotten. On Assignment Day, 12-year-olds leave school and receive their lifetime job assignments. Lina Mayfleet becomes a messenger, and her friend Doon Harrow ends up in the Pipeworks beneath the city, where the failing electric generator has been ineffectually patched together. Both Lina and Doon are convinced that their survival means finding a way out of the city, and after Lina discovers pieces of the instructions, she and Doon work together to interpret the fragmented document. Life in this postholocaust city is well limned--the frequent blackouts, the food shortage, the public panic, the search for answers, and the actions of the powerful, who are taking selfish advantage of the situation. Readers will relate to Lina and Doon's resourcefulness and courage in the face of ominous odds.(Reprinted with permission of Booklist, copyright 2003, American Library Association.)
