The miraculous birth of charcoal gray-skinned daughter to a Celtic queen must endure servitude, prejudice and the King's fury as she trains in secret in order to fulfill her destiny and unite two kingdoms at war. When Queen Shaela had a vision that she would bear a powerful warrior who would unite two kingdoms at war, she was honored. But fate surprised her when she gave birth to a daughter, Da'moree. King Kalen condemns Da'moree to a life of servitude and commands Shaela to raise, Mieko, a child stolen from a handmaid, as the princess. Shaela raises Da'moree and Mieko together but as Da'moree grows older she displays uncanny abilities, which compel the queen to reconsider the prophesy of a long-forgotten legend about The Promise of the Gray Melia. Shaela secretly trains Da'moree in preparation for her destiny but Shaela fears there they may be risking too much. Balancing secrets for a princess and a legendary warrior proves even more troublesome when Da'moree falls in the love with the son of King Kalen's sworn enemy.
