From the bestselling author of Maine and Commencement comes 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 with a wedding. Weaving them all together, Sullivan gives us a sharply observed, witty, irresistible portrait of the thorny, joyful and complicated union that is marriage.
