No marriage is perfect, but Tarryn Fisher's novel, The Wives, explores a domestic situation that is far from the usual. Thursday knows that she shares her husband, Seth, with two other women — Monday and Tuesday — but she's never met them and knows it's best not to ask about them. Everything is OK, until she finds a paper with Monday's real name and address. She can't resist finding out more about this mystery woman, and his first wife, Tuesday, but the more she learns, and the more disturbing details are uncovered, Thursday realises the real reason why Seth didn't want the women to meet.
