This book is emotionally devastating. Poor Mina suffers so much from her insane family, she's been abused, neglected, manipulated and worse, but her strength, bravery and resilience is inspiring. I absolutely love all of the guys, they have such a range in personalities and I loved seeing each one introduced and their whole dynamic as a group, they are all considerate, protective and adoring to Mina. 
I am loving all the crime mystery elements, it is 100% gripping, and I cannot wait for part 2. 
This book has very dark themes, but it is an amazing story of survival, character development, growing romance with a large group dynamic, and the insane hunt for a serial killer.
