Princess Nyamira of Xetaria was chosen to heal a kingdom—and to marry the man who would one day rule it. But when the young princess arrives at court, the cold-eyed crown prince Caelum treats her as nothing more than a political pawn. Years later, when duty demands they wed, he finds himself haunted by the warmth he once ignored and desperate to win back the heart he froze long ago. A Kingdom of Ash & Oath is a lush, black heroine fantasy, slow-burn romantic fantasy where duty collides with desire, secrets bloom like thorns, and love might be the most dangerous vow of all.
