They should’ve made sure.

My Hime. My Princess.
The woman who carved her name into my skin... and then walked away.
Her first mistake.

Now I’m back.
She wants revenge. I brought her a gift.

A symbol of my loyalty. A warning to the fathers who made us enemies.
And maybe... a crown we could burn the world for.

She wants my head on a pike.
I want her on her knees. Writhing. Begging. Ruined beneath me.

It’s war.
It’s us.
And if I die?
I’ll die smiling—with her name on my lips.

Nonstop action! kept me on the edge throughout the whole story, since you can not predict outcomes, the fighting, the steamy and I mean steamy parts not the battle these two will face rather from same blood to friends to rivals.

There will be timelines changing since the prologue was 3 years in the past, I'm not sure is I didn't read Nikolai's story if it happened than, Nadia kidnapped Sho for finding her father, then the time frame when to 'present' that later on we went forward in time 2 years when Sho learns what Nadia's deal was with his father and disappears into the shadows during that time and to the present. Be warned there will be some mentions of children cruelty in different forms.

Together they will have one foot in the Yakuza and a foot in the Bratva!
These two lovebirds love their fighting blades...

Next is Nadia's full brother Alekdandr and their childhood (both Nadia and Alek's, since Lily's father worked with their father)

Sho Matsumoto, son and heir of the Yakuza before what his father did to him to stray from his father sickness to be a strong warrior his mother could have been proud of. What and who Sho is, is due to his father and all this story, he wants to cut down the sickness and clean up the Yakuza to what it was originally was, not the tormented training, child auctions, perverted old men who stand beside his father and left all that sickness turn their group into what it is now. But along the way he met an enemy, and fell for her, Nadia, his Hime, his future Queen.

Vor v Zakone Nadia Petrov 'Hime', Queen of Bratva, father is Boris, Demon of New York, who's on the run. Nadia is the only sister to Nickolai (older half brother same mother, from Bratva King's Secret Twins) and her full brother Aleksandr (soon to have his own story with Nadia's bff Lily). All three siblings were tortured by their father so they all have scares and trauma by who they called father, their mother was sent to them in pieces by said man. Nadia is on a mission to take him out to show the old men of the Bratva who she is, what she can do to prove that she is their Queen.

😈Dark Union of Bratva & Yakuza Mafia Heirs💥

Vivy Skys has set a new standard for dark Mafia by joining Bratva and Yakuza main characters. This is one of the most intense and darkest Mafia books I have ever read. It would make a good movie. Picture a version of “Mr. & Mrs. Smith” but with more sex and violence.

⚠️Danger & Mystery. Haunting Enemies to Lovers Twist

Nadia Petrov is the daughter of a brutal Bratva king who wants his daughter dead rather than have her take over as Queen of the Petrov Bratva. Sho Matsumoto is the son of a Yakuza leader who wants him dead. These two morally black characters have intense chemistry and must overcome brutal rivalry. The passion they share for each other stands the test of time when Sho feels betrayed by Nadia.

This book is perfect for lovers of both male and female alphas and possessive tension. Not only was this a high energy and high action storyline, but the characters were just incredible. The readers are taken on another wild ride…wondering just how Vivy Skys's mind can create such captivating plots.

I don’t give a synopsis when I do a review, so you just have to read the book to find out what happens when a sexy, dominant Bratva heiress and a highly trained assassin Yakuza heir can’t resist each other. I received a free copy of this book and am voluntarily leaving a review.

The book was okay, although it needs editing. Some sentences/grammar don't make sense. I would've like it more if we got to read how Sho became so possessive and in love with Nadia. We just flew right into the middle of the story.

Some things are exaggerated and there are plotholes.
.

Overall, Nadia was not a leader, just a little brat acting up. If she wasn't snarling, she was snapping. She ruined the whole book. 3 stars for Sho only.

Arc review

What a change in pace. Usually we have Male Bratva leaders. The rules are reversed here. Enter Queen Nadia. Nadia is Regal, lethal, dangerous , amazing.
Twisted - real ownership of title of Bratva. Legally - Nadia’s is the eldest, but a female! A psychotic father not wanting a female to rule.

A cat and mouse game with Sho (Shadow) Heir of the Yakuza. Target - find the answer of her sire (Boris Petrov) who decapitated her mother and sent body pieces to her and her siblings ( Aleksandr & Nikolai) as tokens. Nadia is a lot of things but humiliation she is not.

- Raunchy
- Devastating
- Lethal
- Obsessive

Let’s not dilly dally here. This was exceptional. Rarely do we come across a modern read where the female is the head of a Bratva. What Vivy has presented here is more than women’s rights. It’s Nadia’s Petrov stating to the Bratva she is the right person for the position.
Nadia’s most definitely wasn’t the meek princess other rivals named her. Sho was the exception in seeing who she is beyond the layers - HIS, his bloodthirsty assassin, lethal, sex on a stick, I can go on.

Be prepared for a gruesome read. Not for the faint hearted. Vivy expresses her views in her note from author.

For readers of Vivy skys, this will be up your alley. New readers be prepared for the ride.
No furthermore spoiling as this is a must read.

- Power
- respect
- lost souls ->united -> eternity

Whew. Okay. I need a moment to recover because Brutal Union did not just raise the bar—it set it on fire and dared me to chase it. This book is pure mafia mayhem wrapped in obsession, betrayal, and heat that could melt steel.
Sho has been living in the shadows for years, presumed dead, but when he comes storming back into Nadia’s world… it’s like watching a fuse burn down on dynamite. Their chemistry? Volatile. Explosive. Deliciously dangerous. Nadia is the kind of heroine who doesn’t flinch, doesn’t break, and doesn’t bow—not even when faced with the man who both ruined and completed her. And Sho? He’s chaos in human form. Every page was a tug-of-war between love, hate, power, and surrender.
What I loved most? This wasn’t just another dark mafia romance—it was a bloody, brutal, intoxicating chess game where every move hurt and thrilled in equal measure. The tension was razor sharp, the intimacy scorching, and the push-and-pull between them had me reading way past my bedtime (no regrets).
If you like your romances soft and sweet, turn back now. But if you want something raw, obsessive, and wickedly addictive—this is it. Vivy Skys doesn’t hold back, and honestly, I wouldn’t want her to.
⭐️⭐️⭐️⭐️⭐️ Five stars. Brutal. Beautiful. Unforgettable.

Content Warning! See the authors site for the complete list.
It catches you from the first page and you'd better hold on for the rest of this ride!
The world they rule in is dark and dangerous and though these two may "play" with each other, don't test them because you don't want to meet that grisly end.
They're each other's most deadly enemy but they find out that they need each other in more ways than one.
What happens when Nadia has to hunt the only one who sets her soul and body on fire? But who's hunting her and can she trust anyone? She's about to show them, never underestimate a Bratva Queen.
Years ago, she made the mistake of letting him go but Sho will set her body on fire and possess her mind the same way she does his. But nobody hunts his "Hime" but him. And those that would try to harm her? Well, both of them have something for that!
This was dark AND exciting and I devoured it! Please, take heed of the content listing!
I recommend this and this review is my opinion and is not AI generated.

Fighting for their Happiness -
Sho and Nadia’s journey to a happily ever after took me on an adventure filled with drama, suspense, anxiety, violence and steamy encounters in the story that totally engrossed in the pages of the book for the entire day. Vivy Skys blended together Yakuza and Bratva traditions, a codes of honor and loyalty, but with a few added twists, that made the story a much more interesting read. The chemistry between Sho and Nadia was truly epic, but life kept throwing obstacles in their path and of took a fight to the death incident, for them to finally accept their love for each other. This book is worth reading, so I urge you to grab your copy now and make this your weekend indulgence.

ARC Review

If you are looking for a book where the FMC is as much as an Alpha as the MMC then look no further!!! Nadia (Bratva) is almost more brutal & blood thirsty than any of the men in this book. Sho (Yakuza) is Nadia's main rival & is also brutal in his tactics. The chemistry between these two was so hot my kindle almost started on fire 🔥. They both know how to play into each other's weaknesses like it's nobody's business!! I couldn't put this book down! It literally grabs you by the seat of your pants from the first chapter & doesn't let go until it's over (even then you're left questioning wtf did I just read & damn that just happened)!

Highly recommend to anyone who loves mafia books, unhinged characters with pitch black morals, nail biting suspense & hotter than hell spice!!!

Brutal Union came in swinging with knives, blood, and way too much sexual tension for two people who allegedly hate each other. Sho vanishing for years then crashing back into Nadia’s world felt like the kind of drama that makes you mutter “oh no” but keep reading anyway. Nadia as an actual Bratva queen was refreshing, since too often the women get sidelined, and here she’s lethal and commanding. The pacing jumped between past and present, which worked most of the time but occasionally left me pausing to figure out where we were. The writing is sharp, intense, and sometimes over the top, but honestly it fits the unhinged energy of a Yakuza heir obsessed with his Bratva queen. It’s brutal, messy, and kind of hot in spite of itself.

This story is set in Tokyo and the description of the two characters, Sho and Nadia have been so well written, there cruelty to each other and there loving.
She's a Bratva Princess and he's the son of the Yakuza mafia, both have fathers who want them dead.
When these two get together there steamy encounters hold no bounds and changed as to who is in control or not tied up.
Then everything goes wrong when she betrays him to her cost and its three years until they are reunited.
The chemistry is still there but she has to make him trust her again, no matter the cost.
Vivy Skys has written this story in such a way that compels you to keep reading it to the very brutal ending.

First I love anything Vivy writes so I dove into this book very excited. I was asked to review this book by the author and as this was my first time, I felt a lot of pressure to give you an honest review.. first let me say this is a totally different book. It’s too very strong Main characters who in the beginning it’s a struggle, but push through because it’s sensational.. the twist that turns the magnetic pole between them is crazy. Their sexual attraction is off the charts. I’ve always wanted a book to explain the Asian side of the mafia, and this is the encyclopedia for it.. I would give it more than five stars if I could !!!

Nadia and Sho's story is a dark enemies to lovers mafia romance and it did not disappoint right from the first page! I love Vivy Skys way of story telling and her unique and interesting characters! You are pulled right into their drama and angst and at times feel their heartbreak. I enjoyed Brutal Union and it's scorching, obsessive love! If you are a fan of Dark Mafia Romance, morally grey Anti-hero, strong heroines, touch her and die vibes, suspense, hot steamy spice, and possessive and obsessive heroes then this is the book for you!.

If you enjoy a dark and sinister story, this is a book to read. We follow Nadia and Sho. Both have been betrayed by their fathers. Sho has been betrayed by his father, and I thought it wasn't a smart move to have a son as an assassin. It was fun to read how the Yakuza and Bratva come together; they're supposed to be polar opposites, but their feelings can't be held back. I enjoyed their story and I definitely recommend it!

What a great story. This is a dark, steamy, sometimes funny, Bratva and Yakuza story. Sho is an assassin betrayed by his father and Nadia has been betrayed by her father. Both are totally ruthless but somehow they become obsessed with each other. This is a must-read page-turner.

What a story! Both were betrayed by their father's and the only mistake they made was not killing him. He has been in the shadows biding his time and now it is upon him and boy does Sho make an awesome comeback. He and Nadia are a force to be reckoned with.

A Matter of Trust
Sho says Nadia is his. But even though she craves the very breath he breathes around her, how can she? He’s a Yakuza assassin, she’s the Bratva Queen. How can it possibly be? But oh does she want it, almost as much as he wants her! Because when they’re together rational thought is not an option! Thank you Vivy Skys for their incredible story!

A New Legacy

The Bratva and Yakuza, enemies with a determination to undermine one another layered in a forbidden romance. Nadia and Sho at the heart of this story were a fantastic pairing that could not resist the pull. I could not put this book down and kept the pages turning.

Great read

Loved the overall story. Only part bothered me is Nadia thinking her brother Nik would have her killed. He loves her and it’s sad she doesn’t know that.
