A Broken Fairytale

This is a Prequel of The Dark Waltz. I felt it would be a shame if I did not explain what the story emanated from. Seraphina is a Princess to a powerful kingdom. She is also a key character in the destruction of her little brother. She will fight through thick and thin to stay with her coveted Erick, but who is the real villain here, the evil immortal shapeshifter or the cute little Princess?
