At the age of 23, serendipity caused Aude Yung-de Prevaux to discover the truth of her parentage, and in finding out who her real parents were, she tells a fascinating tale. It's the story of Jacques de Prevaux, an intensely ambitious French naval captain who consistently sought higher and more prestigious positions to satisfy his pride - and his need to be the best at everything he did. It is also the story of Lotka Leitner, the captivating Polish Jew who went to chic, 1920s Paris to learn the family business among the great couturiers in the milliners' workshops and famous fashion houses of the time. And it is also the tragic story of how Jacques and Lotka fell fervently in love and were driven to fight together for the liberation of France. Jacques and Lotka were the parents Aude Yung-de Prevaux never knew, heroes of the French Resistance who were buried in anonymous graves and subsequently disappeared from history. Here, she pieces together what became of their lives and in so doing recreates her own past. This biography has a fictional quality like the crackle and hue of a black and white film, although the factual detail often seems to stifle the mania of Jacques and Lotka's love affair. It thus diminishes the sense of urgency and determination that compelled them to fight right up until their execution by the Gestapo.
