A big, sprawling novel about marriage - about those who marry in a white heat of passion, those who marry for partnership and comfort, and those who live together, love each other, and have absolutely no intention of ruining it all with a wedding. Weaving these lives together, Sullivan gives us a sharply observed, witty, irresistible portrait of the thorny, joyful, and complicated union that is marriage. Novel explores the marital foibles of four couples while following the creation of the famous advertising campaign that turned diamonds into a symbol of the hope for everlasting love.
