A slave woman in 1840s America dresses as a white, disabled man to escape to freedom, while a twenty-first-century black rights activist is ‘cancelled’ for denying her whiteness. A Victorian explorer disguises himself as a Muslim in Arabia’s forbidden holy city. A trans man claiming to have been assigned male at birth is exposed and murdered by bigots in 1993.

Lipika Pelham reflects on tales of fluidity and transformation, including her own. From Pope Joan to Parasite, Brazil to Bangladesh, London to Liberia, Passing is a fascinating, timely history of the self.
