We think we know the story of Eleanor Roosevelt--the shy, awkward girl who would redefine the role of First Lady, becoming a civil rights activist and an inspiration to generations of young women. As legend has it, the bane of Eleanor's life was her demanding and domineering mother-in-law, Sara Delano Roosevelt. Biographers have overlooked the complexity of a relationship that had, over the years, been reinterpreted and embellished by Eleanor herself. Through diaries, letters, and interviews with Roosevelt family and friends, Jan Pottker uncovers a story never before told. The result is a triumphant blend of social history and psychological insight--a revealing look at Eleanor Roosevelt and the woman who made her historic achievements possible.
