The body of a young girl is found dumped on the roadside with the silhouette of a doll carved into her skin. When a doll made of skin is found with an abandoned baby, the killer's sick plan comes to light.

To make things more complicated, the cities drug users are being branded with the letter Z carved into their faces. Are the crimes linked or are there 2 people terrorising the city.

The first chapter kicks the book off with a bang. If you aren't a fan of gruesome murders then I would skip this one. I loved that we got to know each of the victims however, it did make it way more heartbreaking when they were killed. Helen is a huge fan of keeping you guessing and I could not put this book down because I needed to know the who and the why.

The secondary plot with the drug users being sliced up definitely didn't detract from the story and was equally as heartbreaking. The fact that Ava puts her job on the line to save people who way too many people think aren't worth it was heartwarming.

Now that Ava has been promoted for a while, her a Luc have settled back into their friendship so everything between them is less awkward and tense. There is still the whole will they won't they question of if they'll ever take their friendship further. I also loved that we got to know the secondary characters more in this book.

Even though this can be read as a standalone and still make sense, I would definitely recommend reading the other 3 first. I also cannot wait for the 5th book to be released. I need more Luc & Ava in my life.
