Jean D'Amérique says he grew up in a neighborhood where "it was easier to find a gun than a book." But as he tells NPR's Ari Shapiro, falling in love with reading and writing changed the course of his life. His new novel, A Sun to Be Sewn, follows a young protagonist growing up in rough circumstances in Port au Prince: her father's a gang leader, her mother's a sex worker. But she's finding her way through poetry – and as the author explains, the medium can carry a lot of political power for people on the margins.
