Paranormal Investigators discussion

I am currently reading Paranormal Technology. The topics are well researched, and explained from a science-based perspective. I like that the author has relevant training and has conducted his own experiments to further research in this field.

I try and avoid these books because they only deal with the science techy aspect of paranormal investigations but not into the resolution. It only covers half the story. I clean houses and deliver people from manifestations, possessions and oppressions.
