Undeniable is a very different book, it was my first dark book. It is very gritty and not a warm fluffy book. It is a very dark at times and displays the raw world of Motorcycle Clubs. The characters are both not perfect, by far, but it is a love story that spans a lifetime. The main characters meet when Deuce is 23 and Eva is 5. Both are visiting their fathers, whom are both Presidents of rival Motorcycle Clubs.
There are some disturbing story elements, so be warned.
For me, I enjoy many different types of books. I'm not always in a mood for a Harlequin love story that wraps a pretty bow on the top. This is gritty and raw, but if you like books like this...you will love it.
