Imagine waking up and finding yourself in total darkness, unable to move further than a few feet because you are chained up. This is absolutely my worst nightmare and immediately swept me into the story. Like the rest of the books in this series, this one is an absolute cracker. Although part of series this book can absolutely be read as a standalone.  There is enough information scattered throughout about the characters back story to keep the reader on track.

Crimes in both Scotland and France have a terrifying connection. Missing body parts, missing people and sex slaves.  It is quite graphic in places though so be warned! A lot going on in this book that kept me interested and gripped and a little bit scared at times! The characters are interesting, complex and with their own histories that further add to the plot.

If you like a gripping crime thriller that keeps you guessing, keeps you on the edge of your seat and keeps you up all night then this is the book. I love police procedural books with a female lead character and I've always liked the character of Ava although sometimes I did find her on/off, will they / won't they relationship with Luc frustrating at times. But, that didn't stop me being their biggest cheerleader. Loved this book and would definitely recommend it to those who like a face paced, edge of your seat thriller that really gets the cogs of your brain turning and turns you into an amateur sleuth!
