Klara and the Sun by Kasuo Ishiguro
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.
Klara and the Sun shows how easily we can exploit even those we claim to love ... a story as much about our own world as about any imagined future, and it reminds us that violence and dehumanization can also come wrapped in the guise of love.
