The good parts are that the paranormal aspect of this book is pretty interesting (if you're able of throwing all your logic out of the window) and it's a fast-paced read with quite a bit of sex, gore and violence. 
 All the rest is extremely disappointing. 
 - The writing style is really simple, and it's all "tell" and no "show" to boot. I like my books to be a little more on the sophisticated side. 
 - The main characters' personalities are practically non-existent, almost like they're just cardboard cutouts. 
 - The humans here are nothing more than food and cannon fodder, and all the characters are basically monsters with little to no moral qualms about killing, so it's hard to feel any sympathy for them. 
 - This is NOT a romance book, it's an erotic urban fantasy. The only "romantic" part here is when Matthew admits that he's falling for Tarrick but that doesn't actually stop him from having sex with other people. And Tarrick doesn't seem to give a flying fuck about Matthew. 
 Hopefully the next book will have more romance, but I highly doubt it.
