“Competing in an Olympics didn't scare her now. The thought of stepping up into the full roar of the crowd, in London, seemed simple and natural and good. It was ordinary days now that frightened her - endless Tuesday mornings and Wednesday afternoons of real life, the days you had to steer through without the benefit of handlebars. Off the bike she was like a smoker without cigarettes, never sure what to do with her hands. As soon as she got off the bike, her heart was expected to perform all these baffling secondary functions - like loving someone and feeling something and belonging somewhere - when all she'd ever trained it to do was pump blood.”

“Her life was one endless loop that she raced around, with steep banked curves so she could never change or slow down. It just delivered her back to herself, over and over and over.”

“Every bitter joule of rage had been converted into speed. She was empty. There was no pain. The air whistled past her ears. She listened intently. That silent music was all there was. It was the sound of the universe showing her mercy.”

“The idea that Sophie could die had always been there, ever since the first diagnosis, and yet it seemed like a bad place on a map, an Ivory Coast, somewhere not urgently frightening because fear itself kept you away from the place. You thought of it as somewhere braver people went, or at least as somewhere you'd have plenty of time to pack your bags for.”

“I smiled down at Charlie, and I understood that he would be free now even if I would not. In this way the life that was in me would find its way in him now. It was not a sad feeling. I felt my heart take off lightly like a butterfly and I thought, yes, this is it, something has survived in me, something that does not need to run anymore, because it is worth more than all the money in the world and its currency, its true home, is the living. And not just the living in this particular country or in that particular country, but the secret, irresistible heart of the living. I smiled back at Charlie and I knew that the hopes of this whole human world could fit inside one soul.”

“But that is the way with killers, I suppose. What is the end of all innocence for you is just another Tuesday morning for them, and they walk off back to their planet of death giving no more thought to the world of the living that we would give to any other tourist destination: a place to be briefly visited and returned from with souvenirs and a haunting sensation that we could have paid less for them.”
