“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.”

“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.”

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

“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)”

“Lina loved her little sister so much that it was like an ache under her ribs.”

“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--”

“Can't it be stopped?" said Lina. She shifted around under her blanket, trying to find a place to sit where rocks weren't digging into her.Maybe it can be stopped at the beginning," Maddy said. "If someone sees what's happening and is brave enough to reverse the direction."Reverse the direction?"Yes, turn it around."How would you do that?"You'd do something good," said Maddy. "Or at least you'd keep yourself from doing something bad."But how could you?" said Lina. "When people have been mean to you, why would you want to be good to them?"You wouldn't want to," said Maddy. "That's what makes it hard. you do it anyway. Being good is hard. Much harder than being bad.”
