At the Waterstones bookstore in London, Jenny Zhang talks about several books that have significantly influenced her writing: Philip Roth’s Portnoy’s Complaint (Random House, 1969), George Saunders’s Pastoralia (Riverhead Books, 2000), and Roddy Doyle’s Paddy Clarke Ha Ha Ha (Penguin Books, 1993). Zhang’s first short story collection, Sour Heart (Lenny, 2017), won the 2018 PEN/Robert W. Bingham Prize for Debut Fiction.
