Plot
When an unspecified global catastrophe looms, an underground city known as Ember is constructed to shelter a large group of survivors. In addition, a small metal box intended for a future generation of Emberites is timed to open after 200 years. This box is entrusted to the Mayor of the City of Ember, and each Mayor passes it on to their successor. When the seventh Mayor dies suddenly, the succession is broken, and over time, the box's significance is forgotten. The box opens by itself at the allotted time, but it goes unnoticed. Several decades later, Ember's generator begins to fail, and food, medicine and other necessities are in dangerously short supply.
At a rite of passage event for all graduating students of Ember City School, Mayor Cole stands before the students as their adult occupations are assigned by lottery. Doon Harrow, the son of inventor and repairman Loris Harrow, is assigned "Messenger" while his classmate Lina Mayfleet is assigned "Pipeworks". Shortly afterwards, the two secretly exchange assignments and Doon is apprenticed to the elderly technician Sul. At home, Lina (a descendant of the seventh Mayor) finds the opened box and enlists Doon's help to decipher its contents. Gradually, they learn that it contains a set of instructions and directions for an exit from the city in the pipeworks.
