What do you do when the king everyone called a monster becomes the only man willing to tell you the truth?
Princess Branwen has spent her entire life preparing to marry the golden prince of Aurelis. Their bond is meant to unite two crowns, preserve a powerful alliance, and confirm the future everyone decided for her before she was old enough to question it.
On the day of the sealing ceremony, her mark is supposed to burn gold before the gathered court.
It burns black instead.
Thornblack roses rise from her blood. The candles bend toward her. The court calls her corrupted, and within hours, Branwen's father agrees to a cleansing that may destroy far more than the mark.
Then Drosten, the feared King of Ashgrave, enters the palace alone.
He claims Branwen is not cursed. He says her mark belongs to an ancient warden bond no priest in Hallowmere understands. When her father refuses to protect her without demanding obedience in return, Branwen makes the first true choice of her life and leaves with the king she was raised to fear.
Beyond Ashgrave's colourless border, nothing is what she was taught. The people do not tremble before Drosten. His kingdom is not built on cruelty. And the feared king behind every childhood warning proves more honest than the golden court that raised her, even when the truth exposes his own failures.
But Drosten is still keeping dangerous secrets.
Branwen's mark answers his shadow. Distance between them brings pain. Thornblack roses follow her steps, and a woman's voice calls from beneath the Hollow Keep, where an ancient Door has been guarded for generations.
As the dark moon approaches, the bond begins to fail, rival kingdoms close in, and Branwen discovers that the golden peace she was raised to preserve may have been built on a lie that is slowly destroying them all.
To survive, she must uncover what her mark truly means and decide whether trusting Drosten will finally give her control of her life, or draw her toward a sacrifice the damaged Binding has demanded before.
Marked by Thornblack is Book One of The Thornblack Chronicles, a dark fantasy fated mates romance filled with slow burn tension, forced proximity, dangerous magic, royal betrayal, hidden bloodlines, and a heroine determined never to become another sacrifice.
Enter Ashgrave, where the darkest mark may be the only thing capable of exposing the truth.
