Behind every powerful man is a trained woman, and behind every trained woman is the Society. It started with tea parties and matchmaking, but is now a countrywide secret. Gossips pass messages in recipes, Spinsters train to fight, and women work together to grant safety to abused women and children. The Society is more than oaths-it is sisterhood and purpose.

In 1926, seventeen-year-old Elsie is dropped off in a new city with four other teenage girls. All of them have trained together since childhood to become the Wife of a powerful man. But when they learn that their next target is earmarked to become President, their mission becomes more than just an assignment; this is a chance at the most powerful position in the Society. All they have to do is make one man fall in love with them first.
