The Daughter of the Sea and the Sky

After centuries of religiously motivated war, the world has been split in two. Now the Blessed Lands are ruled by pure faith, while in the Republic, reason is the guiding light -- two different realms, kept apart and at peace by a treaty and an ocean. A mysterious nine-year-old from the Blessed Lands sails into the lives of a couple in the Republic, claiming to be the Daughter of the Sea and the Sky. Is she a troubled child longing to return home, or a powerful prophet sent to unravel the fabric of the Republic?
