Cat and Fanny have never met. They both live in the same Sydney suburb, but in more than a hunderd years apart. Cat has recently started at a new school on a sports scholarship, and she's feeling the pressure of early morning training sessions and the need for total commitment. Fanny loves to swim and dreams of the Olympics, but family chores and low expectations for girls make it hard for her to fit in any training at all. But one day, in the cool ocean water of Wylie's Baths, Cat and Fanny mysteriously swap places. And they find themselves facing some awkward, amusing and completely unexpected challengers. What's it like to live someone else's life?
