Klara and the Sun

Written from the point of view of an observant android designed to be an AF (artificial friend). Klara observes the world through her window, worshipping the power of the Sun and waiting for someone to choose her. When she and Josie meet it is as if they are destined for each other.
The story is vague as Klara has an imperfect, skewed vision and often does not understand what she observes.
There is a darkness underneath, mostly involving Mr. Capaldi - I am haunted by the way things could have been. Instead it was gentle and melancholy, Ishiguro makes us care about someone who cannot care themselves.
