The Coin follows a Palestinian woman as she pursues a dream that generations of her family have failed at: to live and thrive in America. She teaches at a school for underprivileged boys in New York, where her eccentric methods cross conventional boundaries. She befriends a homeless swindler and the two participate in a pyramid scheme reselling Birkin bags, the value of which "increases, year by year, regardless of poverty, of war, of famine." The juxtaposition of luxury and the abject engulfs her as she is able to con her way to bag after bag, preoccupied by the suffering she knows of the world.

Eventually, her body and mind go to war. America is stifling her—her willfulness, her sexuality, her ideology. In an attempt to regain control, she becomes preoccupied with purity, cleanliness and self-image, all while drawing her students into her obsessions. In an unforgettable denouement, her childhood memories converge with her feelings of existential statelessness, and the narrator unravels spectacularly.
