Nightmare Moon has been vanquished, and the beautiful, gentle Princess Luna now stands in her place. The princess of the night knows she should be thrilled that she has been freed from the prison of her own inner turmoil, but she now has another demon to face: Her beloved daughter, Circe, whose arrival in Equestria Celestia warily allows at Luna’s request.
Having been brought up on the moon, Princess Circe is beautiful, haughty, strong, manipulative, fiercely loyal to her mother, and every bit as powerful as the royal sisters. The young alicorn must cope with the culture shock of her new home in addition to the presence of her aunt Celestia, whom she despises for banishing Nightmare Moon in the first place. Circe stands firmly beside her beloved mother, but she longs for a world without Celestia. Gradually, she fuels Luna’s desire for two things: Celestia’s death, and a government in which the beauty of the night is worshipped and adored.
It doesn’t take long for the mistress of darkness and her daughter to dream of a revolution. The New Lunar Republic will soon rise if everything goes according to plan.
