'Condemned for lacking the horns so prized by her people, One-Horn's daughter must escape by riding one of the legendary flying horses to freedom—if she can stay on its back long enough. But to save a land where the dead walk and ghosts haunt the living, this strange, feral girl—renamed Rhiannon, the rider no one can catch—must convince the human apprentice witches she meets to trust the word of a wild, half-human girl'.
