i went in to this book without reading any other in the series and I will tell you I felt extremely lost. There was so many names and backstory that I didnt really understand. If you jump in to this book, I highly recommend reading the others in the series first. 

while i was lost surrounding some characters and how they play in to everything, what i was not lost on was my enjoyment with Barrett and Reghan. It was really fun watching them fall in love while its a bit forbidden and trying to solve a crime.
