Book excerpt: On a post-college visit to Florence, Pulitzer Prize-winning author Jhumpa Lahiri fell in love with the Italian language. Twenty years later, seeking total immersion, she and her family relocated to Rome, where she began to read and write solely in her adopted tongue. A startling act of self-reflection, In Other Words is Lahiri’s meditation on the process of learning to express herself in another language—and the stunning journey of a writer seeking a new voice.
