Since she burst spectacularly into view with her debut novel, White Teeth, almost two decades ago, Zadie Smith has established herself not just as one of the world’s preeminent fiction writers, but also a brilliant and singular essayist. She contributes regularly to The New Yorker and The New York Review of Books on a wide range of subjects. The New York Times Book Review editor Pamela Paul joins Smith to talk about her writing life and Grand Union, her first collection of short stories.
