According to popular legend and empirical studies, French women were present in brothels all over the world, where they were the most desired and best paid in the business. But were they trafficking victims or willing migrants? In this timely book, Elisa Camiscioli reconstructs the networks and mechanisms of cross-border migrations for sexual labor; elucidates women's motives for leaving and staying; and explains why French migrant sexual labor occupied such a prominent place in the underworld of prostitution, as well as in the imaginaries of anti-trafficking campaigners, immigration officials, and ordinary consumers of vice.
