Exposing lives lived at odds with the idea of a modern Britain in the twenty-first century.

Hsiao-Hung Pai‘s third book, ‘Invisible: Britain’s Migrant Sex Workers’, published in 2013, focused on the story of two migrant sex workers in the United Kingdom.

Pai worked undercover as a maid in brothels in Burnley, Lancashire, Bedford, and Finchley and Stratford in London, as part of her research for Invisible.
