I don't think you should make William a vampire. Maybe something supernatural, but I think a vampire might take away from the story a bit. Great story btw. I am really interested in what she is going to do next.
Really great! What's wong with William? Hmm...maybe self infliction? Sex Addict in the most wrong way possible? Or something supernatural? Whatever it is, the story is really great. Waiting to read hte next chapter!
