When Eleanor discovered Franklin’s betrayal with her younger, prettier social secretary, Lucy Mercer, she offered a divorce and vowed to face herself honestly. Here is an Eleanor both more vulnerable and more aggressive, more psychologically aware and sexually adaptable than we knew. She came to accept FDR’s bond with his executive assistant, Missy LeHand; she allowed her children to live their own lives, as she never could; and she explored her sexual attraction to women, among them a star female reporter on FDR’s first presidential campaign, and younger men.
