Liverpool, 1939. As winter descends on Tuppenny Corner and rumours of war float across the canals, fifteen-year-old Rosie O'Leary must come to terms with her own dramatic upheaval. Forced to say goodbye to all she holds dear and embark on a new life aboard The Kingfisher, her world is suddenly full of uncertainty. But new beginnings open up new possibilities ... When fellow bargee - the handsome Tim Bradley - offers to show Rosie the sights of Liverpool, she jumps at the chance and it's not long before their friendship grows into something more. But when Tim is called up to join the RAF, Rosie's dream of a future together must be put on hold. If Rosie can find the strength to embrace her new life on the canals, there might still be the chance of a miracle this Christmas.
