As far as studying psychopaths, serial killers, and how they might have become the way they are, this book is an absolute gem. I knew when I started this that it was going to be a five star rating within the first few pages. Starting off with the preface, which was amazingly written and enticing the reader to continue reading, we read about the last "celebrity" serial killer of the epidemic years and a name everyone knows: Jeffrey Dahmer. Enough of a blurb to show how lives can change forever in one day and really kickstart the whole book.

Vronsky writes an absolutely fascinating introduction to the "golden years" of serial killers. His writing is clear and concise, and absolutely filled with interesting statistics, facts, and information. Organized by decade based on the adaption of serial killers in the time and featuring prominent killers in the media, we also learn about outside influences each decade that could help cook up the perfect storm that makes psychopaths commit these heinous acts. Things like wars and fathers with PTSD, media such as movies and magazine filled with dark themes in post war times, the politics of race and underreporting of black victims, the brain of a psychopath and the damage that can cause a shift in personality, etc.

One of the greatest parts of this book for me had to be Vronsky's thorough use of his research and citations. I took down so many of his citations for science journals and books that I want to read to do further research. He remains seemingly objective to everything and merely writes things as they are, which is a talent to be respected when dealing with atrocities that break your heart. He is such a good writer that some of the descriptions and reading about the lives of the victims is devastating.

Thank you to Peter Vronsky, Berkley, and NetGalley for the opportunity to read this ARC, especially for such a well-written book.
