Chiaverini reveals the famous First Lady's very public social and political contest with Kate Chase Sprague, memorialized as "one of the most remarkable women ever known to Washington society." Though Mrs. Lincoln and her young rival held much in common-political acumen, love of country, and a resolute determination to help the men they loved achieve greatness-they could never be friends, for the success of one could come only at the expense of the other. When Kate Chase married William Sprague, the wealthy young governor of Rhode Island, it was widely regarded as the pinnacle of Washington society weddings. President Lincoln was in attendance. The First Lady was not.
