I can't stop thinking that maybe two negatives might equal a positive.

I have loved all books by Kele Moon, but her Battered Hearts series was a favorite of mine. So when I saw she was releasing a spin-off series with her Untamed Hearts series, I was just a little excited. And by that I mean I e-stalked the fuck out of the poor author for any and all tidbits about the book and jumped at the chance to read the ARC.

Que linda! I loved this, and I really don't know why it's taken me so long to read it considering how much I loved Crossing the Line by the same author. This is a spin off series and The Viper features Chuito's cousin Marcos, who if you have read the Battered Heats series, you will know is an ex-gangster and current UFC fighter. (His story is next :D)

”You don’t trust thugs.”


I’m a huge fan of The Battered Hearts series and was so excited to read more about the minor characters of that series in this new one. Truthfully, I’m all about getting to Nova’s book, but this author has a few characters’ stories to share with us until I finally get my Nova.

This story is about Marcos Rivera, Chuito‘s hot cousin who is recently released from prison and his fall for Katie Foster, a recently divorced history teacher in Garnet County.

Marcos is an ex-gangster/ car thief that comes from the wrong side of the tracks. Katie is a high-school teacher who was always seen as the good girl. A car accident puts them both in the same path, and a few months later when they find each other again after months of unsuccessfully trying to forget, everything changes between them. But how can the criminal and the good girl find a happy future together?

Half the time I had no idea what he was saying! Did it matter?

Marcos was....he was WOW! He was rough, he was crude but damn was he hot!

I've always loved Kele Moon's heroes. She writes them sexy, rough around the edges, and loyal to a fault. Marcos is all of those things and then some.

The Story

Marcos Rivera is a gang member and a fighter. Wanting to better his life, he went to Garnet only to be met with rejection. On his way to his old life, he collided (literally) with Katie Foster. She's a teacher, a divorce who wants to experience more than what life has offered her so far.

Kele Moon is and most likely will always be, one of my most favourite authors. Every book I have read by her offers the reader a fairytale romance, but in a down-to-earth, dark, gritty and somewhat realistic way. Let’s face it we all want our romantic heroes to be tough, strong and absolute masters in the bedroom, and every one of Kele’s fellas’ fits those requirements To. A. Tee!

He’d stolen things she truly valued. Her heart. Her dignity. Her sanity.

Katie cant get the sexy stranger out of her mind. But with Marco stuck in a gang life, will they have a future together?

The steam in Kele Moon's book always gets my approval. I liked the relationship between Marco and his cousin Chuito. But romance wise I wasn't feeling the love. Also I found Katie a bit stalkerish at the start and then she turned quite needy.

It was okay. I love the sexy time but for me I need to feel the connection and relationship. I still love the Battered Hearts s

Well, by now it is no secret that Kele Moon has very quickly become one of my favorite authors. Anytime that I read something that moves me to the point of stopping what I'm doing and binging out on 5 books in a row, by an author, it's because there is something really special going on. For any of you out there that read some of my reviews, you know that I have had a perpetual problem this year finding books with some actual depth and merit to th
This book just didn't hold my attention at all. I may one day give it a re-read though as I had lots going on in my life at the time; and I am thinking that might be a factor in my not being able to become engrossed in the story.

For myself, it just wasn't what I needed at the time that I was reading it...As far as the writing went, it was good and flowed nicely. This rating in no way reflec ...more

Marcos is a fighter, gang member and criminal.

Katie is a high school teacher.

They meet under some not so great circumstances and have a connection. A negative and a positive should make a negative, right?

Marcos leaves right afterward much to Katie's dismay. Katie does what any woman does who wants to find a man, she places a craigslist ad searching for him. LOL

Marcos finds out and goes back to good ole Garnet to tell Katie to let him go. Only he winds up fucking her in like

“Hurting the things that are most beautiful to me. It keeps happening to me over and over again. I don’t know why, but it does.-Marcos”

The Viper is the first of the Untamed Hearts Series. It is a tender love story between a good girl and a very dangerous man! It is a story of two cousins who have fought their whole life to battle the demons of their past. It is a story of second chances. It answers the question-can love truly prevail?

EVERYONE has been talking about this author. I feel like I should have read her books a long time ago. I’ll be honest. I had this book for a while. I even started it twice. By the third time I told myself NO MATTER what I was going to finish.

The beginning was a bit long and a bit boring, but once you get into it, well, it’s good. It’s not great, but it’s good. Based on the reviews this wasn’t everyone’s favorite book, but I think you need to read the books in

He’d been trying to live an honest life for the past four months simply for the memory of a woman he’d spent five minutes with.

A chance meeting resulting from an accident, changes the lives of ex-con and gang member Marcos Rivera and high school teacher Katie Foster for the better.

Maybe that’s why I can’t give up hoping that one day we’ll talk again. I can’t stop thinking that maybe two negatives might equal a positive. That together, even something as terrible as a car accident can be

Note: Before you read this book, make sure to read Marcos Rivera's Boricua Guide to Spanish and Street Slang, at the back of the book. You'll probably not have any issues guessing the street slang, however, if you lack in your Spanish skills, like me, you'll want to check this out FIRST.

I know this is a favourite of a lot of my friends, but I JUST DON'T GET IT???

I think, honestly, it's my fault. I don't get small town, sexist mentality. This chick puts up with her ex harassing her constantly. She visits her father twice a week to do his washing. Her admittance to wanting to lecture "Super Stud Muffin" (my term, not a quote) because he admitted to "relieving some stress" (hint hint nudge nudge) before seeing her.

The Viper's best part for me was the hero - I loved having a Hispanic hero, Marcos was pretty hot and sexy. The story was a bit different, the hero and heroine met and had an instant connection but the hero really struggled in the story with figuring out what he wanted from his life. He was in a gang and had spent time in jail but didn't see how he could go clean since he struggled to keep a job. There aren't many romances with a guy who isn't older and successful so I didn't mind seeing one who ...more

I just recently finished the Battered Hearts series which is the precursor to this series. I've been looking forward to continuing on in Ms. Moon's MMA fighter world. I knew that some of the younger characters we met in the Battered Hearts series would be the focus of this series, Untamed Hearts.

The Viper (aka Marcos) was a new character to the overall arc. But his connection to the series was not new - he's Chu's cousin. They were raised in the same household and were raised like brothers.

S.M. West

Ay Dios mio!! The passion, desire and sheer WANT between Katie and Marcos was palpable.

I’m not a fan of insta-love and some might argue this was, but I totally disagree. This was an instant connection for sure of two unlikely souls from vastly different worlds that have both had a long streak of bad luck. When they meet, they literally collide in a not so nice way. It was not insta-love but rather a feeling of finding something that you’d been missing your whole life. Both of them

"4.5 Thug Loving Stars!"

The book starts with Garnet native Katie getting into a car accident and meeting Marcos, the cousin of Chuito who we met in the Battered Hearts series.

Marcos and Katie are as different as night and day, and come from completely different backgrounds. An accident brings them together and completely changes them both. Although Marcos walked away, he’s not forgotten the brave “gringa” .
