Klara and the Sun

To me, this definitely outweighs Never Let Me Go. The question that it poses to the reader about AI, I find more interesting and relevant. Also there is a lot of mystery about it which I really like while still remaining clear in its plot. Made me quite sad to finish because I feel like it took way too long to warm up and then the ending was too quick. Ishiguro's writing style is one of my favourite because it's so easy and doesn't require much attention but very imaginative.
I also felt attached to the characters which is always a good sign. I just felt so bad for Klara at the end but I think Josie is one of those characters who just annoyed me so much even though I know you're meant to feel bad for her.
Really want to read it again because I feel like it has a lot more nuance than you pick up the first time reading.
