Roman Stories, the new collection of short stories by Jhumpa Lahiri, captures the tensions of a rapidly-changing Rome, Italy. In today's episode, Lahiri speaks with NPR's Leila Fadel about how growing up as the daughter of immigrants in the U.S. and later moving to Italy as an adult has complicated ideas of home and belonging for her – and how ultimately, home might be of a mental state rather than a physical place.
