Dough. It means bread, the stuff you eat . . . but also moolah, green stuff, money. It's the perfect title for this tough and tender memoir by Mort Zachter. Zachter grows up in a family of workaholics, consumed by the family business, a "bakery" that sells day-old bread. Everyone scrimps and saves. Then, at the age of 36, Mort discovers: they've actually been rich all along. How would YOU deal with that news?
