In this comprehensive, revelatory biography - fifteen years of interviews and research in the making - historian Jane Sherron De Hart explores the central experiences that crucially shaped Ginsburg's passion for justice, her advocacy for gender equality, and her meticulous jurisprudence. At the heart of her story and abiding beliefs was her Jewish background, specifically the concept of tikkun olam, the Hebrew injunction to 'repair the world', with its profound meaning for a young girl who grew up during the Holocaust and World War II.

Ruth's journey began with her mother, who died tragically young but  whose intellect inspired her daughter's feminism. It stretches from Ruth's days as a baton twirler at Brooklyn's James Madison High School to Cornell University to Harvard and Columbia Law Schools; to becoming one of the first female law professors in the country and having to fight for equal pay and hide her second pregnancy to avoid losing her job; to becoming the director of the ACLU's Women's Rights Project and arguing momentous anti-sex-discrimination cases before the US Supreme Court.
