From the best-selling author of Never Let Me Go and The Remains of the Day, a stunning new novel—his first since winning the Nobel Prize in Literature—about the wondrous, mysterious nature of the human heart. From her place in the store, Klara, an Artificial Friend with outstanding observational qualities, watches carefully the behavior of those who come in to browse, and of those who pass on the street outside. She remains hopeful that a customer will soon choose her, but when the possibility emerges that her circumstances may change forever, Klara is warned not to invest too much in the promises of humans. In Klara and the Sun, Kazuo Ishiguro looks at our rapidly changing modern world through the eyes of an unforgettable narrator to explore a fundamental question: what does it mean to love?
