Other than some technical psychology things that I was like "okkkkaay" to I really enjoyed this book. I've never read a book about a person with Antisocial Personality Disorder (APD) who is working with law enforcement to solve crimes of people with possible APD. I do think the amount of times she referred to herself as having APD was a little bit of an overkill but the description of the story was delivered to the reader was top tier! Really enjoyed this book and I play to read the next book in the serious. 

I also love a mystery within a mystery and that's what was happening in this book.
