The author came up with a catchy title to draw people in (taking influence from the excellent "How to Kill Your Family") but couldnt fill the pages with any real substance.
It had more plot holes than a piece elemental cheese. All the murders could have been solved by a 5 year old in 5 minutes. Does DNA evidence not exist in this universe?
It felt like the author googled what a stereotypical millennial womans interests are, feminism, true crime, made in Chelsea, instagram and then cobbled this together. I'm surprised something about Disney wasn't included.
