“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.”

“When someone has been mean to you, why would you want to be good to them?' 'You wouldn't want to. That's what makes it hard. You do it anyway. Being good is hard. Much harder than being bad.”

“Instead of getting at the other side with something just as bad as they did to you - or something worse - you do something good. Or at least you keep yourself from doing something bad”

“Lina couldn't sleep at first, thinking of the old songs and what they meant. Someone, long ago, had hoped that at least a few people would survive and had wanted them to remember her city and the treasure it held, the treasure that was most valuable of all - herself, her family, and all of the generations of people who had lived in that secret place, their purpose, though they didn't know it, to make sure that human beings did not vanish from the world, no matter what happened above.”

“Don’t worry,” said Maddy. “People didn’t make life, so they can’t destroy it. Even if we were to wipe out every bit of life in the world, we can’t touch the place life comes from. Whatever made plants and animals and people spring up in the first place will always be there, and life will spring up again.”

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

“Lina looked out at the lighted streets spreading away in every direction, the streets she knew so well. She loved her city, worn out and crumbling though it was.”
