A white lighters Plight

Leo is a very special man. He is a whitelighter, which means that he died once and was considered pure enough to be given a new role as guardian angel for good witches. He can teleport and he can heal wounds. He is the guardian angel of the Charmed Ones, the strongest good witches there are, but that is not all that makes him special. He was the only whitelighter in the world allowed to marry Piper Halliwell, one of the Charmed Ones. A potion gone wrong now allows him to see the future. But what he sees shocks him to the core. When he asks his superiors, they tell him not to interfere. But will Leo listen, or will he throw caution to the wind and try to save the day?
