The Wives

Thursday is the second of three wives in a polygamous marriage to Seth. He spends a few days each week with each of them, and Thursday has accepted the arrangement because she loves him, though she has never met the other two women. Then she finds a doctor's note in his pocket with the third wife's name on it, and curiosity turns into action.

Thursday seeks out Hannah, the youngest wife, who is expecting Seth's child, and befriends her without revealing who she is. As the friendship grows, Hannah starts turning up with bruises, and Thursday begins to suspect that the man they both call their husband is abusive. Her attempts to uncover the truth about Seth, and about the first wife who says she has left him, push her into dangerous territory and put her own grip on reality in question.

The Wives is a domestic psychological thriller told in Thursday's first-person voice, and much of its tension comes from how far her account can be trusted. It deals with coercive control, abuse and mental health, and its ending divides readers.
