“We were opposites in every way until we grew up, left home, and discovered we were more alike than we'd thought. Sisters only get to be opposites within the family; separated by the world, they become practically identical.”

“Maybe my sister and I shared more than we thought. We were both waiting and wishing for something we couldn't completely control: I wanted to be alone, and she the total opposite. It was weird, really, to have something so contrary in common. But at least it was something.”

“It wasn't that we didn't know history. Even if you only count the real world, we knew more history than most people. We'd been taught about cavemen and Normans and Tudors. We knew about Greeks and Romans. We knew masses of personal stories about World War II. We even knew quite a lot of family history. It just didn't connect to the landscape. And it was the landscape that formed us, that made us who we were as we grew in it, that affected everything. We thought we were living in a fantasy landscape when actually we were living in a science fictional one. In ignorance, we played our way through what the elves and giants had left us, taking the fairies' possession for ownership. I named the dramroads after places in The Lord of the Rings when I should have recognized that they were from The Chrysalids.”

“Hallie and I... were all there was. The image in the mirror that proves you are still here. We had exactly one sister apiece. We grew up knowing the simple arithmetic of scarcity: A sister is more precious than an eye.”

“It was a vicious circle, though. The more gratification we found in our own geniuses, the more isolated we grew. Our home was like an artists' colony. We ate together, but otherwise were absorbed in our separate pursuits. And in this isolation, our creativity took on an aspect of compulsion.”

“The problem is that we don't believe that we are much alike as we are. Whites and blacks, Catholic and Protestants, men and women. If we saw each other as more alike, we might be very eager to join in one human family in this world, and to care about that family the way we care about our own.”
