Seventeen-year-old Amy joins her parents as frozen cargo aboard the vast spaceship Godspeed and expects to awaken on a new planet, three hundred years in the future. Never could she have known that her frozen slumber would come to an end fifty years too soon and that she would be thrust into the brave new world of a spaceship that lives by its own rules.
Amy quickly realizes that her awakening was no mere computer malfunction. Someone-one of the few thousand inhabitants of the spaceship-tried to kill her. And if Amy doesn't do something soon, her parents will be next.
It is always night in the city of Ember. But there is no moon, no stars. The only light during the regular twelve hours of "day" comes from flood-lamps that cast a yellowish glow over the streets of the city. Beyond are the pitch-black Unknown Regions, which no one has ever explored because an understanding of fire and electricity has been lost, and with it the idea of a Moveable Light. But now there are more and more times when the lights flicker and go out, leaving them in terrifying blackness for long minutes. What will happen when the generator finally fails?
The oceans rose, swallowing the lowlands. Earthquakes shattered the continents, toppling entire regions into the rising water. Now, humans live packed into stack cities. The only ones with any space of their own are those who live on the ocean floor: the Dark Life.
Ty has spent his whole life living deep undersea. When outlaws attack his homestead, he finds himself in a fight to save the only home he has ever known.

Beneath the sewer grates and manholes of the city lies a strange and secret world called the Downside. Every Downsider knows that it's forbidden to go Topside, and most fear a collision of the two worlds. But fourteen-year-old Talon is curious about what goes on above ground, and one day he ventures out in search of medicine for his ailing sister.
Kira, newly orphaned and lame from birth, is taken from the turmoil of the village to live in the grand Council Edifice.
