While still mourning over the death of her daughter, Thyri, Siggy Haraldson is surprised to discover she is pregnant with King Horik's child. Worrying for the child's future knowing that Horik attempted to kill Ragnar Lothbrok and his family in Kattegat, Siggy begs for the advice and protection of Ragnar's former wife, Lagertha, and his current queen, Aslaug. A daughter is born, whom Siggy names Moiden, and the seer predicts that she is tied to the fates of three Ragnarssons. Whether that fate be true love, chaos, or Valhalla, Moiden is determined to be the spinner of her own fate and orator of her legendary saga.
