Supernfanfic storie

Dean was just following Sam on another case. His visions had started again, and as far as Dean knew, that meant that Azazel was back. Dean had already lost his brother once to the Yellow Eyed Demon and he was not going to let it happen again. But as Dean chases his brother's vision, the two boys come across not a demon, but a girl. Zai Geller didn't want to be a hunter. She didn't know anything beyond the life she had lived, but when her family died in a tragic fire, she was thrown into the life of the supernatural. With heaven closed and angels on the loose, Sam and Dean have no choice but to take in the mysterious girl.
