Lena Vale is chosen as Fog Valley's sacrificial bride and chained before Black Mountain's feared Giant King. Instead of devouring her, Ares kneels, calling her his lost queen. As Lena escapes her cruel family, she discovers the town has murdered brides for generations to unlock a cursed spirit mine. Betrayed by her sister Selena, hunted by Marcus, and haunted by the dead Queen Evelyn, Lena must choose between fear and love. With Ares's heart stolen and war rising, she awakens her crown, exposes the true monsters, and becomes the Black Mountain Queen by choice, not sacrifice, forever transforming both worlds.
