Melina is a desperately poor woman who lives in Lenù’s apartment building. She’s Antonio and Ada’s mother, and she’s a distant relative of Lila on Nunzia’s side of the family. Melina has an affair with Donato Sarratore, which leads to a vicious feud between Melina and Donato’s wife, Lidia. Melina’s mental health deteriorates after the affair falls apart, and when Donato and his family pack up and leave the neighborhood, Melina collapses entirely. Melina soon gains a reputation as the town lunatic—few people, Lila among them, defend her against the cruel forces of gossip and isolation that infect the neighborhood.
