Black Cake by Charmaine Wilkerson; 2022. Hardcover.

In present-day California, Eleanor Bennett's death leaves behind a puzzling inheritance for her two children, Byron and Benny: a traditional Caribbean black cake, made from a family recipe with a long history, and a voice recording. In her message, Eleanor shares a tumultuous story about a headstrong young swimmer who escapes her island home under suspicion of murder. The heartbreaking journey Eleanor unfolds, the secrets she still holds back, and the mystery of a long-lost child challenge everything the siblings thought they knew about their family and themselves. Can Byron and Benny reclaim their once-close relationship, piece together Eleanor's true history, and fulfill her final request to "share the black cake when the time is right"?
