Madeline Sheehan can put words to paper and come up with a story that is sweet and heartbreaking and hopeful all at the same time. Undeserving was a long time coming and the telling of it was perfect. It was the story of Eva's parents, Preacher and Wheels, and like her story with Deuce, it wasn't pretty and it wasn't clean, but it was theirs. And it was amazing. 
 Throughout the series, we've gotten to know Eva's father, Preacher, through hers and Deuce's eyes. We knew that he was the President of the Silver Demons and we knew that he was badass enough to shoot Deuce for kissing Eva when she was a younger girl. But everything else we thought we knew about him was wrong. From the introspective young man he was when he was released from prison to the man that lived his life respected by his club and feared by his enemies, we see the events that shape him into the person he truly was. He was sensitive, ambitious and loyal. And he was a man that loved three women through his life, each there for him at the time when the previous one was taken. His mother Ginny, his love Wheels, and his daughter Eva. This was a story full of emotion and it shouldn't have been told any other way. 
 For fans of the Undeniable series, this is a must read. For me, it ended a chapter. With Preacher dying of cancer, it was only fair that we get to hear his story and know about his life before it came to its end. My heart ached for him and Debbie, his little pickpocket and "Hell on Wheels" as he named her. We knew all along that there was no true fairytale ending for Preacher, other than seeing his daughter live her leather-clad ever-after. But we never knew him as a younger man, never knew his struggles. Now we understood. Understood his devotion to Eva, his obligation to Frankie, and we understood Eva's mother. She wasn't the junkie that Eva had always been told she had been. She was a young woman, a person with dreams, fears and regrets. Lives had been lived before a five year old Eva had ever met Deuce at Riker's Island, and we finally got the entire heart breaking tale. 
 The emotional part of me felt that this should have been the last book in the series. It came to such a beautiful end, laying Preacher to rest and closing a door. However, with the teaser at the end, the rational part of me is practically salivating to get my hands on ZZ's story next. This story was one long highway stretching through decades and lifetimes, and I'm just not ready to get off this messy and heart-wrenching ride.
