As a writer by profession, I could create an eloquent review, but after reading Undeniable I don't think I can create a cohesive sentence, especially one that isn't littered with curse words. 
 First, I will say a few words about our protagonists. I wanted to lodge Deuce's sac somewhere in the vicinity of his throat. Eva was in need of a thorough bitch-slapping to gain some self-respect- repeatedly with a closed fist. *Hands Deuce & Eva some self-respect* 
 Other than the main characters being a trainwreck and the overuse of 
 BABY & BITCH 
 *shudders in revulsion* I was highly entertained, smirking, sometimes ignited while blushing at Deuce's nasty talk, and laughing at a good portion of the dialogue. 
 The book started perfectly, grabbing my ass in its rough fingers and not letting go. The initial encounters, both platonic and sexual were outstanding. It did wane a bit from the mid-point until the end where the characters were simultaneously acting in&out of character- confusing the f outta me. It was like, Why? How is this driving the story forward? Why do I as a reader have to figure out Deuce's motivations when I'm in his head during his narration? Why is he acting and reacting differently that his thought pattern? I would've liked to hear Deuce's fears instead of guessing that it was the case; I hope it was the case, anyway. Because if not, he was pretty irredeemable otherwise. But I forgave that because I had to know what was coming next even if it was predestined to end a specific way. 
 While I was highly amused at the various ways the word F*ck was utilized, *truly, I was a dirty sailor in a past life* the feminist was clawing, screaming, dying to dig its way out of my throat and throw my beloved Kindle across the room. Yeah, I'm mighty big on respect for a woman, both from men and towards oneself. HUGE trigger for me, that. I understand the dynamic of their world and that women aren't respected as equals. I said I understood it... I didn't say I have to f'n like it, now did I? 
 Second: I pretty much read the book in one sitting and immediately purchased UnBeautifully. Annoyingly frustrating or not, the characters engrossed me, and I loved the storyline for the most part. Curious to see where this series evolves, and do plan on reading the rest of Sheehan's work... just lay off the babies, will ya, PLEASE? I can't swallow that shit. Just can't. Drives me f'n batshit cray-cray. 'k, baby?
