Never Let Me Go — Kazuo Ishiguro (2005)

Kazuo Ishiguro's Never Let Me Go uses its science-fictional conceit — a near-future England in which clones are raised to provide organs for "normal" humans — to explore memory, mortality, and the degree to which people comply with their own oppression when the alternative is hope. Among Ishiguro's finest novels (along with The Remains of the Day), it is one of the most emotionally devastating literary novels of the century.
