Never Let Me Go by Kazuo Ishiguro
The novel describes the life of Kathy H., a young woman of 31, focusing at first on her childhood at an unusual boarding school and eventually her adult life. The story takes place in a dystopian Britain, in which human beings are cloned to provide donor organs for transplants. Kathy and her classmates have been created to be donors, though the adult Kathy is temporarily working as a "carer," someone who supports and comforts donors as they are made to give up their organs and, eventually, submit to death. As in Ishiguro’s other works, the truth of the matter is made clear only gradually, via veiled but suggestive language and situations.
