This is my first fan fiction that is a cross over between Charmed and Supernatural.
SUPERNATURALLY CHARMED:
When Castiel asks Dean for a favor after weeks of silence, Dean can't say no. Little does he know that Castiel has asked him and his brother Sam to help the legendary Charmed Ones. What will happen when two worlds collide? How will the Winchester brothers react when they find out they've been asked to help out witches? Both pairs of siblings struggle to battle some of the strongest demons they have ever faced in order to save something and someone important to all of them.
