Moonie and Mei Ling are sisters. While their parents work their fingers to the bone in a factory, they’re looked after by their grandmother – who’s so brimming over with Chinese mythology and culture that Moonie and Mei Ling can only guess at her age. Eccentric Grandma Wong passes her colourful heritage down to her two wayward granddaughters through stories, songs, and many a purse-lipped reprimand, but the girls' lives are also being drawn forward by the inexorable pace of assimilation and the ever-beckoning American dream, and as fascinated as they are by their grandmother and her world of painful history and Buddhist philosophy, they are also cool, hip American girls with straight-A grades and scores to settle – with the neighbourhood boys who tease them and with the unforgiving media which tells them that they should look like Barbie, and not like Chinese girls.
