Tricia is a shy newlywed, married to a rising attorney working for US Navy intelligence. Charlene is a practiced corporate spouse and mother of three, a beauty and a bully. The two women form a wary alliance as they struggle to balance the pressure to be respectable wives for their ambitious husbands, with their own dubious impulses to "do good" for the people of Vietnam. Sixty years later, Charlene's daughter, spurred by an encounter with an aging Vietnam veteran, reaches out to Tricia. Together, they look back at their time in Saigon, discovering how their lives as women on the periphery - of politics, of history, of war, of their husbands' convictions - have been shaped and burdened by the unintended consequences of America's tragic interference in Southeast Asia. Exploring the disaster of the Vietnam War through the lives built by American wives in 1960s Saigon, this is a virtuosic novel about folly and grace, obligation, sacrifice and the quest for absolution in a broken world.
