I have to add a second one because it is so good, Klara and Sun by Kazuo Ishiguro. Klara a sentient solar powered android who was engineered / created to be an artificial friend to a human child. The designers did not provide Klara with the intelligence of a normal human child let alone a genetically modified 'lifted' human child. The book opens a great big can of ethical worms. AFs are treated as great friends in the beginning but like too many pets are outgrown by their human child companions especially since AFs can't grow. It is a heart breaking story and something that human society will probably have to deal with at some point in the future.

'Klara And The Sun' Is A Masterpiece About Life, Love And Mortality
