What sane woman would consider becoming any man's ninth wife? Bess Gray is a thirty-five-year-old folklorist and amateur martial artist living in Washington, DC. Just as she's about to give up all hope of marriage, she meets Rory, a charming Irish musician, and they fall in love. But Rory is a man with a secret, which he confesses to Bess when he asks for her hand: He's been married eight times before. Shocked, Bess embarks on a quest she feels she must undertake before she can give him an answer. With her long-married, bickering grandparents, her neighbor (himself a mystery), a shar-pei named Stella, and a mannequin named Peace, Bess sets out on a cross-country journey—unbeknownst to Rory—to seek out and question the wives who came before. What she discovers about herself and her own past is far more than she bargained for.
