This remarkable book presents a unique portrait of Ruth Bader Ginsburg, drawing on more than twenty years of conversations with Jeffrey Rosen, starting in the 1990s and continuing through the Trump era. Rosen, a veteran legal journalist, scholar, and president of the National Constitution Center, shares with us the justice's observations on a variety of topics, and her intellect, compassion, sense of humor, and humanity shine through. The affection they have for each other as friends is evident in their banter and in their shared love for the Constitution - and for opera.
