This book is absurd. The author is trying to tie plate tectonics, geologic formations, and environmental contamination to three killers and conclude that the PNW spawns serial killers because of the these items. Environmental contamination has nothing to do with plate tectonics it is human created. Nor does plate tectonics have anything to do with murder. Perhaps the gloomy weather and transient population could be connected to crime but this not even brought up. Don’t waste your time or money on this book.
