Born in 1941, Eileen Tumulty is raised by her Irish immigrant parents in Woodside, Queens, in an apartment where the mood swings between heartbreak and hilarity, depending on whether guests are over and how much alcohol has been consumed. When Eileen meets Ed Leary, a scientist whose bearing is nothing like those of the men she grew up with, she thinks she's found the perfect partner to deliver her to the cosmopolitan world she longs to inhabit. They marry, and Eileen quickly discovers Ed doesn't aspire to the same, ever bigger, stakes in the American Dream. Eileen encourages her husband to want more: a better job, better friends, a better house, but as years pass it becomes clear that his growing reluctance is part of a deeper psychological shift. An inescapable darkness enters their lives, and Eileen and Ed and their son Connell try desperately to hold together a semblance of the reality they have known, and to preserve, against long odds, an idea they have cherished of the future. Through the Learys, Thomas charts the story of the American Century, particularly the promise of domestic bliss and economic prosperity that captured hearts and minds after WWII.
