I was in the book, and the book was in my head, and as long as I stayed inside my head, I could go on writing the book. It was like living in a padded cell, but of all the lives I could have lived at that moment, it was the only one that made sense to me. I wasn't capable of being in the world, and I knew that if I tried to go back into it before I was ready, I would be crushed.
