Sadie Smith - a thirty-four-year-old American undercover agent of ruthless tactics, bold opinions and clean beauty - is sent by her mysterious but powerful employers to a remote corner of France. Her mission- to infiltrate a commune of radical eco-activists influenced by the beliefs of a mysterious elder, Bruno Lacombe, who has rejected civilisation tout court.

Sadie casts her cynical eye over this region of ancient farms and sleepy villages, and at first finds Bruno's idealism laughable - he lives in a Neanderthal cave and believes the path to enlightenment is a return to primitivism. But just as Sadie is certain she's the seductress and puppet master of those she surveils, Bruno Lacombe is seducing her with his ingenious counter-histories, his artful laments, his own tragic story.

Beneath this parodic spy novel about a woman caught in the crossfire between the past and the future lies a profound treatise on human history. Creation Lake is Rachel Kushner's finest achievement yet - a work of high art, high comedy and irresistible pleasure.
