Evelyn has been married to her husband for forty years--forty years since he slipped off her first wedding ring and put his own in its place. Delphine knows both sides of love--the ecstatic, glorious highs of seduction and the bitter, spiteful fury that descends when it's over. James, a paramedic who works the night shift, knows his wife's family thinks she could have done better. Kate, partnered with Dan for ten years, has seen every kind of wedding--from the Nantucket beach wedding to the Irish castle wedding--and has vowed never, ever, to have one of her own. And Mary Frances Gerety, a young advertising copywriter, knows exactly what marriage is: it's a diamond ring on a girl's finger--and it's her job to make sure everyone believes that. Weaving these lives together, Sullivan gives us a sharply observed, witty, irresistible portrait of the thorny, joyful, and complicated union that is marriage.
