His name was Castiel, and he was an Angel of The Lord. Annabelle had never felt safe, not even with Castiel. But, one day she got the visit that could change all that. Not only did she become more enlightened to her true self, but she became closer to Castiel. The oncoming war wasn't going to stop Annabelle from getting what she wanted, and she wanted Castiel. But, she had to win the battle, to win the angel.
