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.
