About the title
According to FBI estimates, only one in five serial killers is caught by the law, while the rest remain free. Agent Lee Harker is hunting one of these elusive monsters, known as the Soul Collector. For over a decade, his victims have been entire families, whose members killed each other for inexplicable reasons. The closer Harker gets to uncovering the killer's identity, the more clearly she realizes there is a connection between them.
