A battle is looming over Scotland, but fourteenyear-old Lady Mary is safe in Inverness Castle, awaiting her marriage to a young squire. As the ward of Lord and Lady Macbeth, Mary has nothing to fear—until her father betrays the king and is hanged as a traitor. In an instant, both her father and her future are lost to her forever. Condemned to spend her days as a scullery maid, Mary becomes a firsthand witness to Lord and Lady Macbeth’s relentless pursuit of power. As the events of Shakespeare’s tragedy unfold around her, she discovers that destiny is hers to change—and that the power to save the Scottish throne from tyrants lies in her hands.
