 The best sports biography book that I've ever read, and I'm not even a tennis fan, but if you're a reader, get a copy of Open by Andre Agassi. It's 400 pages of how much he hated tennis. But it's how tennis was tied into his relationship with his father, who I think was an immigrant. I think he was a boxer, if I remember correctly. And he decided when the boy was two years old that this kid was going to be great at tennis.
