In the Blood Moon Era, vampires rule the kingdom while werewolves command its armies, and hybrids are despised as cursed outcasts.
After her young son dies in a royal conspiracy, the lowborn hybrid maid Seraphina feigns madness and disappears into the forbidden Forgotten Tower, where she learns the deadly art of Blood Charm seduction.
Three years later, she returns to the palace wearing a magic-sealing collar, determined to seduce the vampire king, destroy those who betrayed her, and uncover the dark truth behind her child’s death.
