A curious thing about Frederika Mathilde Louisa Saskia was that, once she had got accustomed to being in a new setting—which never took more than a couple of hours—it was as if she’d never been anywhere else. When she’d been in Texas, answering to "Saskia" and floating down the Brazos, or tucking into some brisket at T.R.’s mega gas station in the suburbs of Houston, it had taken mere moments for her to forget about the fact that she was the scion of a royal family that went back many generations and lived in palaces in a faraway country. She was fully immersed in the moment of chopping the celery with Mary Boskey or screwing Rufus on the train, and that was that. She could have kept riding that train forever.
