Aaron's Crossing

About a month ago I finished a book called "Aaron's Crossing". It was a really great book and I would love it to be a true story. It supposently is. It's about a woman who is walking through a graveyard and senses that there is a presense there. The spirit follows her home and she helps him to cross over. He crosses over and then returns to tell her the story of what happened before his death, and the story of the limbo he was in before she walked into the graveyard. It was a very interesting and sad book.
