For ten years after the events of 'Witch Wife' Irene Shannon lives on the coast of Georgia with her husband, her sister, and her niece. She's believed to be dead, and she likes it that way. They all live in peace until one day the British come, making accusations of treason. With Fiona married to the heir of the Hayter gunpowder dynasty, the entire Shannon-Hayter family is on the hook for William Hayter's dealings with Peruvian rebels.
Their contact Maeve Mendoza is the daughter of a prolific sailor and adventurer, who chose his family over his duty and died in disgrace when she was a child. Maeve was once a helpless girl, saved and later trained by Irene and Merrick and completely devoted to them. She arrives at the estate and declares Peru's independence, and that their protection extends to the Shannon-Hayters.
To lead negotiations, the British princes send for General Sing St. James. Known as the Gravedigger Knight, she's a prolific fighter and military figurehead. She was groomed for greatness from a young age. Built to be a weapon, just like Maeve. Through political maneuvering, dinner parties and sieges and attacks by ice monsters, the women become entangled. As they grow to respect and care for each other, they come closer to an inevitable end; both sides can't win in a war.
