This book made me fantasize about angel and demon, when the demon was fell, inside-out, in love with the angel. 
 I first read the second book in the series, so i met Connor first, then Bowen and Sera, the protagonists in this novel. I've always enjoy Tessa Bailey's books. My first book was in the Line of Duty series, about a hostage negotiator who met his match in a form of kindergarten teacher. It was HOT it was sweet, what it was not is, dark, like this book. 
 But if you dig tortured alpha male, then this book is for you, because Bowen was all that. Some crime boss with a tortured heart. His heart might be black, but he still got one, and it's beating painfully, made him all sort of wrong person for the job. Until he was called by the police captain, to help an undercover rookie, Sera, the angel. 
 I really like Bowen. How he was so maddeningly into Sera, and how he done a poor poor job in stopping his feeling. But why should he, when Sera made him desperately trying to be a better person. 
 But there were too many secrets, too many intrigues. Can their feelings for each other conquer it all? But hey, what is love if not powerful, right.
