One of my favourite books in the series- I genuinely could not stop reading it (sorry to my teachers who I ignored to read this book <3). This book had some of the most shocking twists of the whole series- I could never predict what was going to happen next (especially with the ending). Brennan's emotions through the whole book are also so interesting- as she deals with the guilt that comes along with unsolved cases and everything else that comes with her job.
