“But what I wanted back had never really been there. He was a temporary illusion, a mirage of water after walking in the desert. I had made him up. And he could have killed me. You've got to stop the ride sometimes. Stop it and get off.”

“I had been so worried about him not wanting me that I hadn't stopped to know if I really wanted him--if he was right for me.”

“Maybe I had been making a greater monster of him than he really was, or maybe I was still under his influence, for I was certain that he wanted me to believe he was no more than a harmless man who happened to use vampirism to get what he desired. Some remnant of his mesmerism was still upon me. I had never been able to shake the feeling that he was tucked away in a corner of my mind, that he could read my thoughts, know what I was thinking. He had done something to me, but what that was, I had never been able to discover. All I knew was that the feeling had been with me since the morning I woke up and found myself in Venice.”

“I've wished for things and never really had the chance...It's time to stop dreaming and do something about it. You've got to know what you want, then...go.”

“I even had this idea that the knife stopped working, that after a certain time it just stops working for you, when your number is up. I thought maybe it was me who had done it. That I killed him just by growing older, and being ready to replace him.”

“My father told his acquaintances about that for years, even though both Hannah and I had given up on wormholes and the Child Genius series very soon afterward. That must have made my father sad, as it had made him sad when we stopped being excited about family vacations, when we stopped being open about our interests, and left home and pursued lives of our own. It was just regular growing up, of course, the kind everyone does, but it still made him sad, I know, like the memory I have of the time he dropped me off at the train station when I was going back to Chicago. I could see him through the window of the train, but he couldn't see me through the tinted glass. From up in the train, he looked so small. If he'd seen me, he would have smiled and waved, but he didn't know I could see him, and the sadness on his face was exposed to me then. He looked lost. He stood there on the platform a long time, even after my train started pulling away, still trying to catch a glimpse of me waving back.”
