It’s the summer of 1987 in Swift River, and Diamond Newberry is learning how to drive. Ever since her Pop disappeared seven years ago, she and her mother hitchhike everywhere they go. But that’s not the only reason Diamond stands out: she’s teased relentlessly about her weight, and since Pop has been gone, she’s the only Black person in all of Swift River. This summer, Ma is determined to declare Pop legally dead so that they can collect his life insurance money, get their house back from the bank, and finally move on. But when Diamond receives a letter from a relative she’s never met, key elements of Pop’s life are uncovered. She is introduced to two generations of African American Newberry women, whose lives span the 20th century and reveal a much larger picture of prejudice and abandonment, of love and devotion.
