Almost the first thing I think of with Kazuo Ishiguro is the beguiling, perplexing mixture of the innocence and craftiness of his narrators, the puzzle of what they do and don’t know and what they are willing to tell us at any given moment. But today I find myself thinking about the ways in which the world looks back at those narrators, as in Never Let Me Go, which Ishiguro has described as an “alternate history,” and in Klara and the Sun, an emotionally realist approach to sci-fi.
