Never Let Me Go
This quietly heartbreaking and provocative novel is equal parts British boarding-school story, dystopian science fiction, and Kafkaesque fable about conformity. While the premise (human clones harvested for their organs) seems ripped from the headlines, the absence of plausible science in the plot suggests that the clones are a metaphor for the myriad ways we sacrifice our human potential by failing to question authority.
