Tayari Jones published An American Marriage in 2018, which won the Women’s Prize for Fiction and became an Oprah’s Book Club selection. It is one of the more precisely realized American novels of the decade — a story about a wrongful conviction and the marriage it destroys that manages to be simultaneously a social novel and an intimate one. The follow-up has been anticipated for years. Kin is appearing on early-year best-books lists before the critical apparatus has fully deployed.
