As a United States senator since 1973, Joe Biden has been an intimate witness to the major events of the past four decades-from the Vietnam War, to the fall of the Berlin Wall, to the aftermath of the 9/11 attacks. In Promises to Keep, Biden movingly recounts growing up in a staunchly Catholic multigenerational household in Wilmington, Delaware; marriage, fatherhood, success and failure in the Senate and on the campaign trail; and his leadership of powerful Senate committees.
