EternallyHurt, if you can track down the book called Hungry Ghosts by Joe Fisher, I think you'd find it very interesting (and it's a great read, too). It was published about 20 years ago. I'm not sure where you are, but there are quite a few 2nd hand copies in USA, UK and Australia available on abebooks,
