Kim, you know the movie From Dusk Til Dawn the scene where the demon is chasing after the man that is carrying the blood of God with him in the bottle that he uses to get rid of the demon for a little while? The song they use in that scene reminds me of some of the characters you use in The Hollows. Don't remember the name of the song but it is dark and oh so good. Thought it might inspire you. Love this series.
