Sin Wager: A Bratva Bloodlines Romance

Rate this book
I just wanted money.
For medicine.
For my brother’s life.

I never meant to steal from the Bratva.
But the Radich gave me bets to place.
Numbers. Envelopes. Rules I couldn’t question.

Then Misha Vetrov noticed me.
Cold eyes. Tattooed hands.
The track’s new king of sin.

He pressed me against his world of fire.
And I gave in.
One kiss. One night. One reckless surrender.

Now I’m carrying his baby.
And he doesn’t know.

The Radich want me silenced.
The Vetrov want answers.
And Misha? He wants me under him, under oath, under lock and key.

But how do I keep his secret safe—
When he’s the kind of man
Who always finds the truth?

Vera is trying to pay for her brother’s medicines, her father a labourer hard working as well
Vera works at the local racing stadium where she is a stable hand and also cares for the horses in her care and also, she tries to earn additional money by additional jos so that she is able ro pay for her brothers’ medications. His fight against leukaemia is hard and at seventeen his bravery would put an adult to shame, he never complains and she fights for every new treatment available.
Batya her father is proud of his daughter but he knows that the additional notes she brings home with her is for more than simple stable work and he knows that this is going to put her in danger. Vera is aware that these bets she has been placing is a risk but she will not leave her brother wanting family is everything.
Misha has been sent to find the culprits behind the betting irregularities that have occurring on the track and decides that Vera is obviously being used by a syndicate that is praying on the fact she is trying to save her brother by paying for medications that are only available by purchasing and he is starting to see some improvement.
As Misha spends some time getting to know her, he begins to realise that this has become more than a simple job and he also knows that her and her family’s life is in danger and has to discover who is using her, then find the best way to help them.
This is a simply wonderful read and I guarantee that all readers will be as captivated by this simply wonderful plot as I have been.

I thoroughly enjoyed the book and look forward to reading any future publications; keep up all the wonderful writing.

This is another book taken in Russia around the Bratva horse racing track, which was okay. I had a hard time picturing this story in Russia as I did in the first book I read in this series about this track. It seemed that it was loosely based in a country ran by a dictatorship versus a racetrack in a democracy. I know that the racetrack was owned by the Bratva, but so much of what took place didn't feel like this story took place in Russia.

It began very slow, had some editing issues and was an age-gap romance between Vera and Misha. The writing was a bit "wordy" and repetitious, but overall was acceptable. The premise of this book was good in that it focused on a naïve Ukraine woman who worked at the track who got caught up in criminal activity in order to bring in extra money for her brother's cancer treatment.

Misha and Vera's romance was more of a seduction than an actual attraction. The relationship is a slow burn with much of the story centered on the race track. Misha seduces Vera both sexually and mentally to help him bring down the criminal activity against the Bratva who seemed to be an up and coming threat in the Russian criminal underworld. The love story wasn't just built on sex, it was built on a man who was good at convincing Vera the he "saw" her and wanted to provide protection for her. Misha was a lifeline to a woman that was drowning in something that she didn't completely understand and saw no way out.

The baby was no surprise because they have become typical in this genre.

Ariana has written a bratva romance but it a different take in the usual ones. Which is a refreshing thing when you read so many mafia/bratva romances they can start to become similar. The plot to sin wager is set at a racetrack.

The FMC Vera is a Ukrainian immigrant living in Russia with her batya (father ) and her brother Elvin who is 17 and has cancer. Vera works as a stable hand at the track where she is coerced into placing bets for someone it starts small and becomes bigger and bigger until the track is loosing millions and the bosses at the track get involved unfortunately for her the track is run by a bratva family the vetrovs. Misha MMC chooses to go a different way in trying to get info out of Vera he seduces her and appeals to her natural affinity for horses and sacrificing herself for her family. Vera ends up pregnant and during the investigation period she starts noticing things about misha that he has a dangerous side and he has started to fall in love with her despite only initially seducing her to get information. Vera is instrumental in helping misha end the vetting scam. She is strong, capable, loving and loyal and everything he didn't know he needed.

I liked this book, it took me a little while to get into it but once i did I couldn't put it down, it's well written, easy to read and refreshingly different to the usual genre.

I came for the Bratva intrigue, but I stayed for Misha Vetrov. Sin Wager hit me like a freight train—dark, scorching, and utterly unputdownable. I felt every reckless gamble, every pulse-raising kiss, and every moment of tension as the Radich and the Vetrov tightened their grips around her.
Misha is exactly the kind of alpha that makes your pulse spike—cold, commanding, and tattooed with danger, yet impossibly magnetic. Watching her navigate a world of sin, power, and forbidden desire had me clenching my jaw one second and swooning the next. And that secret pregnancy? Yeah… I was living for the drama, the lust, and the heart-wrenching stakes all rolled into one dark, delicious package.
Ariana Cooper knows exactly how to make you ache for her characters while keeping you flipping pages until your fingers hurt. Dark. Dirty. Devastating. Every second in this book is an adrenaline shot straight to the heart.
⭐ 5 stars. If you crave Bratva chaos, alpha domination, and a heroine who fights for love on her terms, Sin Wager is your ultimate fix.
Heart racing, teeth gritted, and me helplessly lost in every sin-soaked twist—Rebel is officially chained to Misha Vetrov until the last page burns down!.

Book four of the Vetrov Bratva and you are in for a treat with Misha who wants information regarding irregularities in the Racetrack for his Pakhan.
Vera works at the racetrack but is also placing really big bets for a woman who is blackmailing her.
Vera's brother has cancer and unless she places the bets he will have the treatment.
This is just the bones if thus story but one that will keep you locked in place until you have read the whole book, just like i did.
Brilliantly written again Ariana Cooper.

Sin Wager is a unique take on a Bratva romance. It's Misha and Vera's journey and it's quite a story. A migrant on Russia, Vera's and her father work very hard to take care of her sick brother. Affording his medicine is costly so Vera takes on another "side" job at the track and this is where things get sticky. Misha is sent in to straighten things out and Vera wasn't what he had bargained for at all, but needed more than he realized. Their story is fast paced, intense and dramatic.

Misha may be almost twice her age but he can’t stay away from Vera. A dramatic read with Bratva, drama and violence, family and steamy moments too.
