Raised in the working-class towns of Scranton, Pennsylvania, and Wilmington, Delaware, and with lackluster grades in school and no particular goals, Joe Biden shocked the nation in 1972 when he became one of the youngest elected senators in U.S. history. Over the course of four decades, he carved a legacy for himself as one of the most respected legislators in the country, and was a close friend and partner to President Barack Obama, who valued his vice president's vast experience in domestic and foreign affairs. Yet Biden's political success has been matched by personal tragedy and countless challenges. Within two months of being elected in 1972, Biden lost his wife, Neilia, and his young daughter in a tragic accident-a loss that brought him to the nadir of despair and shook his resolve to stay in politics. He suffered two brain aneurysms and career-threatening gaffes and miscues. In 2015, he lost his eldest son, Beau, to brain cancer. Now, Biden is back in the spotlight as the frontrunner in a crowded Democratic field challenging Donald Trump in the 2020 presidential election. Based on exhaustive research by one of Washington's most prolific journalists, including numerous exclusive interviews with Biden's confidants and family members, as well as President Obama and the former vice president himself, Joe Biden goes beyond conventional biography to track the forces that have shaped a man who, with his plainspoken style and inspiring life story, has resonated with millions of Americans and whose work has shaped modern American life.
