Southern Californians have donated lots of supplies to help those displaced by the Lahaina fire. Shipping containers are full, but there are other ways to help. Ivy Pochoda’s latest novel, “Sing Her Down,” focuses on two formerly incarcerated women making their way to and through LA in the early days of the COVID pandemic. Art historian Thuy N.D. Tran aims to shed light on a lost “golden era” of South Vietnamese modernism by piecing together collective memories from the diaspora.
