In 40 CE, in the Au Lac region of ancient Vietnam, two daughters of a Vietnamese Lord fill their days training, studying and trying to stay true to Vietnamese traditions. While Trung Trac is disciplined and wise, always excelling in her duty, Trung Nhi is fierce and free-spirited, more concerned with spending time in the gardens and with lovers. But these sisters' lives --- and the lives of their people --- are shadowed by the oppressive rule of the Han Chinese. When Trung Trac and Trung Nhi's father is executed, their world comes crashing down around them. With no men to save them against the Han's encroaching regime, they must rise and unite the women of Vietnam into an army.
