In 1002, 15-year-old Emma of Normandy crosses the Narrow Sea to wed the much older King Athelred of England, whom she meets for the first time at the church door. Thrust into an unfamiliar and treacherous court, with a husband who mistrusts her, stepsons who resent her and a bewitching rival who covets her crown, Emma must defend herself against her enemies and secure her status as queen by bearing a son.
