City of Ember

by Jeanne DuPrau

The City of Ember
The city of Ember was built as a last refuge for the human race. Two hundred years later, the great lamps that light the city are beginning to dim. When Lina finds part of an ancient message, she’s sure it holds a secret that will save the city. Now, she and her friend Doon must race to figure out the clues to keep the lights on. If they succeed, they will have to convince everyone to follow them into danger. But if they fail? The lights will burn out and the darkness will close in forever.
The People of Sparks
Lina and Doon have led the citizens of Ember to an exciting new world. They’ve been given safe haven in a small village called Sparks, a place filled with color and life. But they’re not out of danger yet. Although Sparks seems like the answer the long-suffering Emberites have been hoping for, tempers soon escalate. The villagers have never had to share their world before, and it only takes a tiny “spark” to ignite a battle between the two struggling groups. Lina and Doon will have to work together to avoid a disaster not only for their people, but also for the people of Sparks. 
The Prophet of Yonwood
Nickie will grow up to be one of the first citizens of the city of Ember. But for now, she is a girl who has just moved to the town of Yonwood. There, she discovers a place full of suspicion, where one citizen’s visions of fire and destruction have turned everyone against each other. Eager to take her mind off her father’s absence as he works on a mysterious government project, Nickie reads her great-grandfather’s peculiar journals, spies on a reclusive neighbor who studies the heavens, and meets a strange boy who is fascinated with snakes— all while keeping an eye out for trouble. But is it already too late to avoid a devastating war?
