Nina Revoyr brings us a compelling story of race, love, murder, and history against the backdrop of Los Angeles. A young Japanese-American woman, Jackie Ishida, is in her last semester of law school when her grandfather, Frank Sakai, dies unexpectedly. While trying to fulfill a request from his will, Jackie discovers that 4 black teenagers were killed in the store he ran during the Watts Riots of 1965—and that the murders were never solved or reported.

Along with James Lanier, a cousin of one of the victims, she tries to piece together the story of the boys' deaths. In the process, Jackie unearths the long-held secrets of her family's history—and her own. Moving in and out of the past, from the shipping yards and internment camps of World War II; to the barley fields of the Crenshaw District in the 1930s; to the means streets of Watts in the 1960s; to the night spots and garment factories of the 1990s, Southland weaves a tale of L.A. in all of its faces and forms.
