Basic premise of the book is that Character A's wife dies, and when she dies, he loses his soul, because she "took his soul with her when she died." He meets a woman, and has to protect her from other soul suckers. I'm just at a loss as to how to get the info.
Now on to my question. I could have sworn that I remember a mythology around beings that suck the soul, not vampires, but another "monster" for lack of a better term. I've searched and found various poems and song lyrics,and a book reference but not anything like what I am looking for.
If I'm on the wrong track with my search terms, I'm more than happy to do the research, but I'm just not finding what I am looking for with what I came up with on my own.
