Filled with Ali Smith's trademark wordplay and inventive storytelling, here is the dizzyingly entertaining, wickedly humorous story of a mysterious stranger whose sudden appearance during a family's summer holiday transforms four variously unhappy people. Each of the Smarts—parents Eve and Michael, son Magnus, and the youngest, daughter Astrid—encounter Amber in his or her own solipsistic way, but somehow her presence allows them to see their lives (and their life together) in a new light. Smith's narrative freedom and exhilarating facility with language propel the novel to its startling, wonderfully enigmatic conclusion.
