The Grand Duke's Daughter

...They call him the Masked Tyrant-a name whispered across battlefields and inked into blood-soaked headlines.
Grand Duke Alvarado, the faceless monster of the Dukedom, a man whose mask is said to be as permanent as his cruelty. No one has ever seen his face. No one who has dared to stand before him has lived long enough to describe it.
While he wages endless war on the frontlines, his only child has been hidden away.
Since infancy, Astra Alvarado has lived in a quiet, nameless village far from the Dukedom's reach-raised in peace, sheltered from power, and deliberately kept ignorant of the man who shares her blood. The Duke was never a father to her-only a myth she learned about through crinkled newspapers and hushed conversations that stopped when she entered the room.
Each article painted the same portrait: merciless, unfeeling, unstoppable.
And Astra was afraid.
Afraid of the mask.
Afraid of the bloodstained legacy she carried.
Afraid of what would happen if he ever discovered her existence.
Everything changes on the eve of her debutante.
The headlines spread faster than fear itself: the Grand Duke is returning home. For the first time in years, the Masked Tyrant will leave the battlefield and reclaim his seat of power.
And Astra's greatest question is no longer who her father is-
-but whether he will kill her when he finally comes to claim what is his.
