The fragile ones was my first book by the author.

I enjoyed it quite a lot as it was a bit more than the police procedural usual storyline and I really liked Katie. While this is the fifth book in the series and she makes a few references about past moments, I feel like I can read it as a stand-alone with no problems at all. 

I used to watch Cold Case tv episodes and while I was reading this book; it reminded me how much I loved a complex detective heroine and always wanted to know what drives her to find the culprits after so many years. Here’s the same thing, Katie and McGaven are trying to find out what happened with the two sisters that disappeared a few years ago and why there’re so many twists in their investigation. 

It intrigued me to know what was all about the tattoos and if they will find a new body out next. 

A serial killer on the move, an interesting investigation, and great detective teamwork in this book.
