Most tennis fans were introduced to Naomi Osaka as they watched her win the 2018 US Open final in an unforgettably controversial and dramatic victory over her idol, Serena Williams. Since then, Osaka has galvanized the tennis world --- and gained attention across the culture --- not only by winning three more majors but by finding her voice. But until now, the story of the Haitian Japanese American Osaka family’s journey across the world to follow their tennis dreams --- and how their youngest daughter found her power off the court --- has remained little known. It is a story unlike any other, and Ben Rothenberg’s biography not only shows where Osaka came from but also where she's going as she returns to competitive tennis after a year on maternity leave.
