My whole life I've been fascinated with true crime documentaries, investigations and I know my serial killers. At first glance I thought this was another fiction book with criminal minds vibe but reading the description its so much better and left me with wanting more. In media about crime and killers we always hear about the killer, victims, and family of the victims... we rarely hear about the investigator and how they deal with these gruesome cases. By just hearing about some of this cases makes me feel uneasy I can only imagine the investigators, detectives, etc. who are experiencing first hand and try to figure out why and who and have to relive the moments the victims lives to figure out the killer
