Growing up in the 1930s, Edie Windsor hadn't always been bold. In fact, she was someone who played by the rules and loved math. Numbers added up right every time and equal meant equal. But when the US government refused to acknowledge the loving relationship of over forty years between her and her spouse Thea Spyer, Edie made a bold move and sued the US government! In this comprehensive picture book biography, acclaimed author Michael Genhart shares the story of LGBTQ icon Edie Windsor and the pivotal case that set the stage to take down the Defense of Marriage Act (DOMA). In United States v. Windsor, Edie's tenacious spirit proved to the Supreme Court and the world that love is love and equal means equal.
