“A darkness different from Ember's, but just as frightening...”

“There is so much darkness in Ember, Lina. It's not just outside, it's inside us, too. Everyone has some darkness inside. It's like a hungry creature. It wants and wants and wants with a terrible power. And the more you give it, the bigger and hungrier it gets.”

“She realized all at once that Doon, thin, dark eyed Doon, with his troublesome temper and his terrible brown jacket, and his good heart---- was the person she knew better than anyone now. He was her best friend.--City of Ember--”

“Then came "The Song of Darkness," the last of the three songs, and the one most filled with longing and majesty. The soul of Ember was in this song. Its tremendous chords held all the sorrow and all the strength of the people of the city. The song reached its climax: "Darkness like an endless night," sang the hundreds of voices, so powerfully the air seemed to shiver. And at that moment, the lights once more went out. The voices faltered, but only for an instant. Then they rose again in the darkness, stronger even than before. Lina sang, too. She stood up and sang with all her might into the deep, solid blackness.”

“That's the city I see in my dreams, Poppy. It isn't like Ember at all. The sky is light and the buildings are tall and sort of sparkle." (Lina)”

“They lifted their faces to the astonishing warmth. The sky arched over them, a pale, clear blue. Lina felt as though a lid that had been on her all her life had been lifted off. Light and air rushed though her, making a song, like the songs of Ember, only it was a song of joy. She looked at Doon and saw that he was smiling and crying at the same time, and she realized that she was, too.”

“What you need to learn, children, is the difference between right and wrong in every area of life. And once you learn the difference, you must always choose the right.”
