London! When Simone invites Carly and Dora to stay with her parents in England on holiday, they're looking forward to an adventure - but they're not expecting to go back to the past, let alone face discrimination, disease and danger! Thrust back into London of over a hundred years ago, when women were not allowed to have real careers, they meet one woman who is about to change it all: Florence Nightingale. Through war and peace, Carly and her friends learn that courage sometimes means owning up to your mistakes.
