'Ellie and Tess are the adopted Chinese twin daughters of an Australian couple who travel the world frequently for their careers. They have come home to settle in Dixon's Crossing for an unspecified period and although they are happy to be in Australia, they miss their good friend Fei Fei from China. A lost letter announcing Fei Fei's surprise visit for a two-week holiday, is forgotten as her arrival in person is great cause for celebration.' (Source: CMIS website)
