Hellfire

The Vikings MC: Tucson Chapter #6

by Cathleen Cole, Frank Jensen

She’s his best friend’s little sister, but he’d risk everything to have her…

Hellfire
Smoke would kill me if he knew all the dirty, depraved things I want to do to his little sister. For years, I’ve been forced to look and not touch.
She’s been mine since the first time I saw her, even if she doesn’t know it.
But when yet another threat to the club comes out of the woodwork, I decide I’ve had enough.
No more waiting.
Life’s too damn short.
If only it was that simple, but we’ve got enemies coming at us from all directions.
Just as I vow to make her mine no matter the cost, they attack. Once the dust settles, things might never be the same…

Kit
I’ve been in agony for years, watching my brother’s best friend flirt with anything with two legs and a pair of tits.
Tiny pieces of my heart chipped off every single time, breaking pieces of me I don’t think I’ll ever get back.
But no matter how badly I wanted the strong, gorgeous biker, I knew he could never be mine.
So, imagine my surprise when he tosses me over his shoulder like a caveman and tells me I’m going to be his old lady.
It feels too good to be true, suddenly getting everything I’ve ever wished for.
And it turns out it just might be…

Another one of this author’s books that I could not put down, it had me at the edge of my seat the entire time with all the suspense action in all the twists and turns

Everything about Kit had been driving him insane since Hellfire met her all those years ago. Only trouble was she was his best friend’s baby sister (Smokehouse) See the thing was he had a bond with Smokehouse from their military time plus the mc bond

Both Kit and Smokehouse had grown up in the MC life and Smokehouse often put himself in between her and men who wanted to date her, with all that went on in the previous book with how close to home things got with most of the females, Hellfire Thought to himself enough is enough and he needed to share his feelings with kit…. He could deal with Smokehouse later



I’ve loved the banner between Hellfire and Smokehouse From the beginning, Boy did the author turn up the banner between these two in this installment

And Holy Smokes did toxic and Butcher really cut loose on this one

So, you might think that this was just all about the romance between kit and Hellfire…. Nononoo we can’t forget about the drama with Italians, that will keep you On the edge of your seat….. Oh my gosh and that curveball that the author threw at us with Idaho …..

so, before you know it you’ll see me back in Tucson with the next installment

Ooooooooooooooooooooooooooooooooooohhhhhhhhhhhhhhhh soooooooooooooo good

[T.P.A. · Rating 4 out of 5]

I knew these two would be a sweet couple. Ten years, ten years loving someone that you do not dare approach out of your respect for her brother. Hellfire is just such a teddy bear - protective, sweet and absolutely devoted to his heart's desires. The main heroine is rather cute as well, she has been raised in this life and I have to say that I did like how she handled quite a few situations. Although the main characters have known each other for a long time, coming together has its challenges and it was such a pleasant experience seeing them discover new things about themselves.

There were some pretty hilarious moments with the guys here as well as tension in regard to the Italians. This community that the MC is different, not the typical MC where there is plenty of OW drama, which I did appreciate. Looking forward to reading about some of the other MC members and their journey.

AAAHHHHHH I can’t even!!! I knew this was going to be a good story. Towards the end of Smokehouse we start to see some of Hellfire and Kit’s connection and we already know that Smokehouse has no problem with his best friend dating his sister. However, Hellfire and Kit don’t know that and it was super fun reading those chapters where they are worried about his reaction and reading about Smokehouse trying to mess with them. Then watching them navigate their new relationship all the while dealing with the clubhouse problems…. AMAZING!!!

Great series!

So this one was probably not my fave. I like to have a little more on page relationship development. I know they had known each other from before, but it just seemed to jump right in to a "you're now my old lady" when they've only kissed a couple of times. I did like how it skipped the overbearing, "you are my best friend, but you s*ck and can't date my sister" shtick ❤. I do think its worth reading. Still entertaining and important to the overarching story arcs.

First Impressions
Hellfire is the story that has been building over the series. This is where we see the romance that actually gets put in place between Hellfire and Kit. Its been obvious that they have both loved each other from a distance, but they have hesitated to actually act on how they feel due to the fact that they have so much love and respect for Smokehouse (who is Kit's brothers and Hell's best friend). I was intrigued to see how this author team would be writing this trope. It is one of my favorites and surprisingly it wasn't as angsty as I expected it to be, but I am good with that. But there were some plot happenings that I did love to see actually.

First Line
A tight ass in blue jeans filled my vision as I came down the stairs.

The Main Protagonists
The Hero: Hellfire
The Heroine: Kit

Summary
Hellfire as been wanting Kit for years....but it hasn't even entertained the idea of pursuing her until now. He knows that he could be bringdown down hell on them both if he does pursue her, but he is at the breaking point of not resisting what he feels for her. Kit has had to watch the man that she has loved since childhood, constantly be pursued by women and have to stand by and doing nothing. But when Hellfire makes his interest in her more bold....to the point of kissing her in front of her brother....she is realizing that her dream could come true. But she is still fearful that he could fall out of love with her....but Hellfire is determined to show that his love is true and sincere.

What I Loved
Hellfire was such a beautiful story and might be my favorite of the series. I loved that we got to see their relationship and connection to be built throughout the story. And their relationship get kicked off pretty quickly on this one. I did enjoy the brother's reaction though. From the previous book, we know that Smokehouse has known of their love for each other and isn't against it....but he hasn't said that to Hellfire or Kit.....and we see how playful he is with them. It was interesting to see how it all plays out, and while it wasn't exactly what I expected....I still had a fun time with it. We also have a plot dealing with the mafia in the area and how they are trying to take down the club. And I was actually thrilled that we get to see the evils revealed of one of the women in the club that we saw from book one. I had a suspicion she was always not good and we see her true colors being truly revealed here. It was heartbreaking because of what Hellfire and Kit have to go through because of it....but seeing their courage and how they come together because of it. It really digs deep on the strength of their love and what it does for each of them.

What I Struggled With
Nothing much....I did find it interesting how soon they had sex after she was stabbed in the stomach lol It felt not practical in any way.

Overall View
Hellfire is a thrilling installment that kept me on my toes both in regards to the plot and the swoons. I was so hooked into this story, this pairing had such bright chemistry that shone so brightly and it was a true MC gem that I didn't want to put down.

Steam/Spice Explanations

Steamin' up the room -the sexual content is more explicit in the language and tone, heavier amount of sexual scenes.

[Alexandra · Rating 4 out of 5]

This was a fun book and a really fun couple. Thoroughly enjoyed, perhaps the most out of all the books in this specific series so far.

They're well matched. Chemistry was there. Called each other out on their BS and went to bat for each other. I liked them a lot.

[Mrs T · Rating 4 out of 5]

Every time a new book in the Vikings MC series comes out, I'm all of a flutter.  And every time,  I say that the MC is my favourite,  but Hellfire takes top spot, for sheer dominance and softness in one gorgeous,  rugged, biker package!

Hellfire has never acted on his long term feelings for Kit, after all she is his best friends sister,  and the MC family bonds are everything.  But after the danger the Vikings have seen recently,  he has realised that time can be short in this life and he needs to act on his feelings before its too late.

Kit was made for Hellfire, she is no wallflower but has a vulnerability to her that needs protecting.

The banter between Kit's brother and Hellfire is great. As is all the found family interaction between the members of the club and their 'old ladies'.  Of course,  being the Vikings,  there is danger around them, but that is what makes the love stories that evolve, stand out.

Love is in the air. So are bullets.

This is the story about health, fire and kit. These 2 had on each other since they were young. And how fire is smokes? Best friend. The story is the best friend's little sister kind of trope and if you've read the books before. You know that the story continues with the Italian mafia. And everything that's going down with the club. The story is one of those romances where they friendly or together. And everything that can go wrong. Does and throw in hellfires? Cousin named pixie, who is mentioned in almost all the books so far. As being someone, you need to keep your eye on.

[Jeanie's Kindle · Rating 5 out of 5]

Started off slow

When Hellfire and Kit began,I figured being established club members would make their story boring. Not so! They quickly developed a story with the Italians and one mole in the club. There's always someone trying to climb up the social ladder. Pixie was Hellfires cousin, using his good name she thought she was entitled to a cut and biker husband.

Well written... But again the ending sucked

[Jenni · Rating 5 out of 5]

4.5 stars

Hellfire is a combustible blend of forbidden longing, raw emotion, and the relentless danger that defines The Vikings MC: Tucson Chapter. This installment takes the classic best friend’s little sister trope and injects it with the grit, heat, and high‑stakes tension that fans of the series have come to expect.

Hellfire has spent years burying his desire under loyalty and self‑control, and the result is a hero who feels like a live wire—coiled, frustrated, and one heartbeat away from snapping. His internal tug‑of‑war between brotherhood and obsession gives the story its emotional spark. When he finally decides to claim what he’s always wanted, the shift is explosive. His protectiveness, his intensity, and his willingness to risk everything for Kit make him one of the series’ most compelling anti‑heroes.

Kit’s perspective adds a heartbreaking layer to the story. She’s spent years watching Hellfire flirt with everyone but her, each moment chipping away at her confidence. Her vulnerability is palpable, but so is her strength. When he finally turns his attention her way, her disbelief feels painfully real. She’s not a passive love interest—she’s a woman who’s been hurt, who’s learned to guard her heart, and who has to decide whether the man she’s always wanted is worth the risk.

The chemistry between Hellfire and Kit is molten, but the book never lets you forget the danger closing in around them. The club is under attack, enemies are circling, and every moment of tenderness is shadowed by the threat of loss. This tension keeps the pacing sharp and the stakes high. Their relationship isn’t just about desire—it’s about survival, loyalty, and choosing each other even when the world is falling apart.

Like the previous books, Hellfire delivers a mix of action, angst, and steamy romance that hits hard. The emotional payoff is satisfying, the character arcs are well‑earned, and the MC backdrop adds the perfect amount of grit. Fans of forbidden romance, protective anti‑heroes, and heroines who refuse to break will find this installment especially addictive.

Hellfire is a dark, fast‑paced, and deeply emotional ride that proves some loves are worth every risk—even when the cost might be everything.

Read if you like;
-Read in one sitting
-Motorcycle gang
-In love for years
-Twists

Honestly; I will die on a hill for this series 😩😍, it’s by far my favourite and I always look forward to reading them!

Hell & Kat, they’ve had this desire and love for each other for years. They’ve pushed it aside for friendship and brothers! However, finally it comes to a head it the best way possible!

We have the slowest of burn, which is burning hot when they get down to business - and I mean come on we’ve all been waiting for this moment🥵!

My only criticism would be that there wasn’t as much tension as what we are used to in the other books!

I love seeing and reading about the rest of the gang and how they mess with hell 😍

As always Cathleen & Frank always provide the drama and action which keeps you hanging on till the very end. That cliffhanger was as always jaw dropping and I was not expecting that at all!

[Sarah_A6210 · Rating 5 out of 5]

Another fantastic book

I love this series, I’m 6 books in so I must!!
I have loved the MMC Hellfire in the other books so I couldn’t wait to read his story, especially when it involved his best friend’s sister, the FMC Kit.

They have both liked each other for years but never strayed from more than being friends. Neither wanted to ruin relationships within the club or with each other but both have not really been living while waiting for the other.

Hell decides enough is enough, Kit is his and he doesn’t care what he has to do or who he has to get approval from, it’s happening and everyone else can just get on board or keep quiet.

Loved that this was a no nonsense we’ve waisted years and we’re doing this attitude. There was no slow burn and although this was fast it still felt right when they had been such good friends for so long, they already knew each other

I love this biker series it’s one of my favourites!

Family, what is family?

Hellfire and Kit. The couple that has teased us with possibilities the whole series. They become a couple pretty easily at the beginning after many years of flirting, but then Pixie and their problems with the DA and the Italians lead to some dangerous moments for the two of them. Their relationship took what seemed to be a bump over that interaction, but they made it through and we got to see their relationship grow stronger and see more of how the MC feels about each other and the women. Butcher and Toxic are my favorites and I loved their scenes. Butchers talk with Kit was oddly sweet and the Toxics song when he went to help Butcher, hilarious. The ending had a cliffhanger I was not expecting and I am even more excited for the next book!

[LJ Metzger · Rating 5 out of 5]

I've been so excited for this story! We get a glimpse into Hellfire and Kit flirting with each other in Smokehouses story but of course they want to be respectful of Smokehouse so they never go farther than flirting.
Turns out this whole time they both had been hiding their feelings for each other, well they thought they were hiding them.
Their story is a beautiful one of how friendship can blossom into romantic love.
Of course we still get some action and some edge of your seat excitement.
Another well written romance with the perfect amount of action, excitement and spice!
Can't wait to see what's coming next!

[The Book Collector · Rating 5 out of 5]

Hellfire & Kits story was a story we’ve all been waiting for. Two people who were longing for each other but didn’t want to cross lines until Kit was in trouble. Hellfire was tired of waiting. He wanted to make Kit his & finally claim the only women who had his heart.

Absolutely loved this book. It was everything & more. Cathleen Cole & Frank Jensen did it again with another amazing book.

You could feel the steam rolling off the pages. Hell & Kit had that in full. There definitely was laugh out loud antics from certain characters, I would love to see books of their own. Can’t wait for the Berserker MC. After that bomb visit can’t wait for the Idaho book!

[Amanda Davies · Rating 5 out of 5]

Perfect MC club story

If you like MC club bad boy romance stories, then this is a perfect series for you. To get a true sense of the story, you have to read them in order, so don't start with this one... while each story has its own biker and girl romance, there is an ongoing storyline across all of the books.
These are true Mc club stories, so there are mentions of unaliving and other trigger scenes, so check the trigger warnings.
I'm loving this series, having accidentally come across it a few days ago... I'm already finished book 6. I literally can't leave the series along. I will miss this MC club when I finish the last book.

[jamies_bookreads · Rating 4 out of 5]

Enjoyed

4.25/5 🌟

How can you not love a ‘brother’s best friend romance’? I’m so glad Hellfire (MMC) found the strength to make a move on Kit (FMC). These two have been sneaking peeks at each other throughout the series. While Hellfire is ready to jump in with both feet, Kit is a little scared to rock the friendship. However, admiring their love for one another becomes the easiest thing they have to face, as family members cause problems that leave them both facing trouble.
"If he’s got the wrong impression, we may as well have fun before we get into trouble."

[Wendy Livingstone · Rating 5 out of 5]

Amazing!!

This is the sixth book in this phenomenal series and this is Hellfire and Kit's story.
This is a well written story which is an action packed emotional roller coaster, with family, friendships, loyalty, witty banter, humour, danger, suspense, intrigue, challenges, crazy shenanigans, and love which all leads to an entertaining, twisted, haunting, tragic, and steamy addictive page turner.
I look forward to reading more from this talented author whose work I highly recommend.

[Aubrea · Rating 3 out of 5]

Pretty average for the series. Bc they were already friends for years it wasn’t like they had much to get to know. I do think that Hell didn’t prioritize her after the funeral. The club stuff I get taking priority, but his family stuff could wait. Something else I didn’t get is if his family business is doing so well then why don’t they hire another person or two? Not bad but the ending just wasn’t what I wanted bc I don’t think the other men would prioritize their parents and extended family over their women so that was disappointing.

[Wendy Smith · Rating 5 out of 5]

Such an exciting read. I absolutely loved Hellfire and Kit’s story ❤️❤️❤️ waiting years to reveal their feelings to each other, finally it’s out in the open and excepted by everyone, Smokehouse, Kit’s brother gives Hellfire his blessing. That doesn’t mean life is easy for the couple, they have chaos and drama filling their lives. Both are put in dangerous, life or death situations. It was a thoroughly enjoyable read. 100% recommend this book to everyone ⭐️⭐️⭐️⭐️⭐️ you will not be disappointed 😎

I loved Hellfire and Kit together. They both had feelings for each that they kept hidden, or at least tried to.
My favorite part was seeing how their relationship evolved from friends to lovers.
Things didn't always go smoothly for them, but they overcome.
Filled with drama, some action, spice and more!! I can't forget the humor either.
This story had my attention and gave me a few edge of your seat moments.
I loved it!

Another fantastic read

Hellfire and Kit's story is now my favourite.

Hellfire and Kit's chemistry is off the charts hot, and they are perfectly matched in every way.

We also get to hear from the other brothers and, most importantly, we Butcher and Toxic, who are quickly becoming my favourite brothers.

Their story is action-packed with jaw-dropping moments and a hea, and the ending has left me pinning for Locks book.

Again, another great book :)

I have been waiting for Hells and Kits book for a while and it did not disappoint. Their story has been building up for years until Hellfire finally went after his girl. Of course, getting to see the previous characters and seeing all their opinions on this relationship was amazing. I can’t wait for Butchers and Toxics book as well as figure out more on who this Idaho man is we’ve heard about…..
