This was an okay/alright book.
A lot focuses on the author and how she grew up and her while writing.
It does give information about the GSK but it's nothing new, though I did enjoy how she wrote the victims stories and brought attention to the victims in this.
I did skip paragraphs about the locations history as that wasn't relevant to the killings, some parts should've been edited out as they add nothing to the story and they read well without them.
However, this was the work of an internet detective/ sleuth who brought case files, befriended investigators and tried to solve the mystery of the killer, which she didn't do. I see many criticise that she had nothing to do with his capture, but I'll say that she shed light onto this case with the work she'd done, overall it was decent but if you know the case I wouldn't say you'd benefit from reading this.
