The City of Ember by Jeanne DuPrau
Plot summary: “Lights shine in the city of Ember—but at the city limits the light ends, and darkness takes over. Out there in the Unknown Regions, the darkness goes on forever in all directions. Ember—so its people believe—is the only light in the dark world.”
The City of Ember was built as a refuge for the human race, but after about two hundred years, the resources are running out and there is a shortage of light bulbs which will result in total darkness. Lina finds a fragment of an ancient message that she must decode to save the city.
Clear writing, a suspenseful mystery, an escape scene, and a journey to an unknown place push the reader to read the sequel. This is the first of four science fiction fantasies. (The City of Ember, The People of Sparks, The Prophet of Yonwood, The Diamond of Darkhold)
When I read this book, my mind kept thinking it was Christian allegory. I wonder whether that was the author's intention.
