I had no intention of reading "Undeniable", because of the disclaimer that this book is raw, dark and disturbing. But then I found out that the hero is 18 years older than heroine. And like that I was sold. Because age difference is my weakness, my guilty pleasure in romances. 
 This book definitely left a strong impression on me. I think Eva and Deuce are the most dysfunctional couple I've ever read about. And it says something, as I've read books like "Fifty Shades of Grey", "Bared to You", "Beautiful Disaster" and many more like this. The heroes were seriously messed up, and their life choices were awful and brought nothing but misery. I was rooting for them at the beginning, but then I thought they will be better apart and then I just thought that all the characters needed serious help. 
 It is hard to rate this book, because it wasn't bad. It kept me interested and involved. I couldn't stop reading even if I tried. It was wild ride and in the end it left me emotionally drained. But it was very disturbing for my taste. So many sick shit happened there. All these drugs, whores, killings, cheating, rapes are not for my sensitive mind :) I like my books tamer. So I think I'll stick to Kristen Ashley calmer version of motorcycle club life in her "Chaos" series. 
 P.S. I've never read a book with so much swearing in it. The word "fuck" is used 1160 times. This is a lot for such a short book.
