I was pleasantly surprised with this book. I love all of Gena Showalter's books & Wicked Nights didn't disappoint. 
 I liked that the author incorporated some of the LoTU characters into this book. Now onto the good stuff......Zacharel is a hot, badass warrior angel who falls in love with Annabelle who's being tormented by demons. It's a gradual romance that happens throughout the whole book with some twists & turns along the way. 
 If you're into PNR I recommend this book! You won't be disappointed. 
 Now I have to wait patiently for the 2nd book of the series to come out!
