All In by Billie Jean King is published on 9 September (Viking, hardback, £20)
When I was a girl I’d sit in my elementary school classroom in Long Beach, California, staring at the big pull-down map of the world, and daydream about the places I’d go. England, Europe, Asia, South America, Africa! Even then, I felt that borders had no hold on me. They connected me. I can’t remember a time when I didn’t have a restlessness, an ambition, and an urgency. As much as I loved my family and hometown, I always knew that my life would somehow take me beyond their embrace.
