In a manor by the sea, twelve sisters are cursed. Annaleigh lives a sheltered life at Highmoor with her sisters and their father and stepmother. Once there were twelve, but loneliness fills the grand halls now that four of the girls' lives have been cut short. Each death was more tragic than the last -- the plague, a plummeting fall, a drowning, a slippery plunge -- and there are whispers throughout the surrounding villages that the family is cursed...

On a remote island estate, Annaleigh Thaumas, the sixth-born of twelve sisters, enlists the aid of an alluring stranger to unravel the family curse before it claims her life.
