Jean Serjeant, the heroine of Julian Barnes's wonderfully provocative novel, seems ordinary, but has an extraordinary disdain for wisdom. And as Barnes follows her from her childhood in the 1920s to her flight into the sun in the year 2021, he confronts readers with the fruits of her relentless curiosity: pilgrimages to China and the Grand Canyon; a catalog of 1940s sexual euphemisms; and a glimpse of technology in the twenty-first century (when The Absolute Truth can be universally accessed).
