They can't share her. But what if she loves them both?
College student, Marnie LaFontaine doesn't know what happens to a soul when the body dies. She likes to think that it moves on to a better place, or maybe it's given a choice to linger amongst the living to watch over loved ones. That would mean that the parents she lost at such a young age continue to watch over her.
She never would have guessed what actually happens. She'll find out soon enough. Hopefully she lives through it.
