A Certain Slant of Light by Laura Whitcomb

A ghostly story about a woman who is caught up in time –she died over 100 years but she cannot pass over to the other side because of a moral baggage that burdens her. She meets a young teen boy who can see her and they fall in love.  Not longer after, things become quite complicated and very unpleasant for the two lovers. This is the type of story that when you are finished with it, you will continue to think about it.  It will not be soon forgotten. A very interesting read.
