Together we'll make magic...Who had conjured whom?She seemed to remember Oliver suggesting this once before, but she hadn't really appreciated the importance of his question. Was she the dream? Was Nao the one writing her into being? Agency is a tricky business, Muriel had said. Ruth had always felt substantial enough, but maybe she wasn't. Maybe she was as absent as her name indicated, a homeless and ghostly composite of words that the girl had assembled. She'd never had any cause to doubt her senses. Her empirical experience of herself, seemed trustworthy enough, but now in the dark, at four in the morning, she wasn't so sure.
