So good. I spent a lot of time thinking about this book. What are the ethics and implications of attaching a head to another body? I also wondered a lot about Travis and Cate. At first I thought he was really rude to not pay any attention to her wishes at all, but then I thought about myself at sixteen and remembered that for him, it was like he had fallen asleep and it was the next day, but it was five years for everyone else. I had more sympathy for him after that (although I still wish he had listened to her.)
