Serena Williams dominated women's tennis for more than 20 years. She won 23 Grand Slam singles titles as well as made her mark in doubles. Coco Gauff is still young and can't boast the same numbers--but is rising to the top of the tennis world. Can a rising star and a retired player be compared to decide who's the greatest? Readers have a chance to do just that in this dynamic book. Stats, stories, and biography of each player is included alongside full-color photographs of Williams and Gauff in action.
