Three years after the revolution destroyed her royal family, Princess Rien is released from her dungeon imprisonment only to be forced into a strategic marriage with Duke Lysian of Roche Noir.

Broken by the labels forced upon her by others, Rien spent years sinking deeper into her own darkness. But surrounded by Lysian’s warmth and unspoken devotion, she begins to find the courage to face her true self.

Together, they learn that faith and promises can defy destiny itself—and that under the same starry sky, they have always been each other’s ultimate sanctuary.
