All In by Billie Jean King

Before Serena, before the equal prize money, before any of it - there was Billie Jean King, picking fights for women in tennis. All In is her autobiography, and it covers everything: 39 Grand Slam titles, the Battle of the Sexes, the eating disorder, the years spent in the closet, and the exhausting work of building women's professional tennis from scratch. One of the great sports memoirs, by someone who understood that the court was only ever half the battle.487 pages. Hardcover.
