"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 she lives for racing, but family chores and low expectations for girls make it very hard for her to fit in even the occasional training session. Cat and Fanny have never met. They both live in the same Sydney suburb, but in different worlds, or at least different times: Cat in current-day Sydney, and Fanny in 1908. But one day, time slips and they swap places. As each girl lives the other's life, with all the challenges and confusion it presents, she comes to appreciate and understand herself and the role of swimming in her own life." --publisher's website
