Sweet Obsession

Savage Vow #1

by O.S. Feathers

LUNA ROJA

He came for my sister.
The scarred, brutal Bratva king from Russia, the one whispered about in mafia circles like a ghost story, traveled halfway across the world to claim her. But my sister was too fragile for a man like him. I tried to protect her.
I didn’t know I was the one he truly wanted.
From the moment Misha Petrov saw me, I became his obsession.
He struck a deal with my father and took me instead. Forced me into a sham marriage, dragged me into his icy empire, and made me pretend in public that I belonged to him. But behind closed doors, the lines began to blur. I hated him. I needed him.
And then, I ran.

MISHA PETROV

She thinks she escaped. She thinks I’ll let her go.
But Luna Rojas was never going to leave me, not truly.
I burned everything that stood between us, including the man she thought she loved. The one I had to kill. And when she fled to attend his funeral, I followed with five hundred men and a vow carved in blood.
I cleared the graveyard. Claimed her—body, soul, and screams, right there, over his bones.
Because if I can’t have her love… I’ll take her fear. And I haven’t even started yet.

About the author

O.S Feathers writes dark, twisty love stories about morally questionable men and the fierce, brilliant women who bring them to their knees, sometimes literally. She has a soft spot for arranged marriages, possessive antiheroes, and heroines who know how to shoot or at least threaten with style.

She drinks too much coffee, lives for slow-burn tension, and has never met a knife-to-throat scene she didn’t love. When she’s not writing, she’s probably researching obscure Russian swear words, rewriting a spicy chapter for the third time, or convincing her characters that therapy is not, in fact, the enemy.

If you like your love stories messy, dangerous, and just a little unhinged, she’s got you.

In desperate need of an edit!!!!

My god this book could have been great but by about 50% I had to give up for the sake of my sanity. Headings, chapters and breaks weren't properly spaced or fonted. The characters had this amazing ability to be in about 14 different places at once while simultaneously wearing about 3 layers of clothing. In one page the FMC went from wearing a funeral dress, to trousers and back to the funeral dress again as it had magically reappeared after being ripped off 🤷🏻‍♀️
The characters couldn't stay consistent. Not one of them from the protagonists to tertiary roles.
There was also a blinding amount of spelling mistakes that genuinely made me dizzy.
I was so looking forward to this book as from the blurb it had all the troupes I enjoy but the further you go the less sense any of it makes to the point I have to wonder how heavily AI was involved.
In short, so much promise to lead only to great disappointment, this author needs to edit this and fast.

Great idea for a book terribly done. The glow was off took forever for them to actually be in bed together or make any sort of a real relationship.

Had to dnf at 44%. The story sucked me in but the execution was so bad, it became almost unreadable.

I'm considering 2-3 stars, why?

It was a twisted book and I don't mean a dark matter or something like that. Throughout the whole book I felt like I missed a lot of information like I skipped some detailes or so. But I didn't skip anything, unfortunately... So it was weird like I couldn't get their feelings, but for them it was normal because they had a lot of off page things happening that we just didn't know apearently..

I didn't let the reviews get to me previous of the book, but since this was a freebie I could have known..

At first I thought okay this is going to be good, but it became obvious really quickly that it wasn't..

And she didn't even confess to Misha who was the actual killer.. And so much more. Also we don't get to see if Oleg is okay and Nikolay is just per accident that we get that info.. Like for real? If you make things happen disclose everything so we know..

I don't think I want to even give book 2 a go if it's as over the place as this one..

Dnf @ 14 %

I’m all for badass fmcs who know their worth and how to fight but omg she was so reckless. Like girl use your head please. Not getting Misha’s pov until ch 8 was annoying because I couldn’t stand Luna after 4 chapters let alone 7.

It’s okay

The writing is okay. Graveyard scene is nice but the excitement ends there. It’s an easy read and was good enough I finished, but lacking in flow and unique content. It’s okay.

No, lines were all cliche and cheesy, minimal dialogue, characters 2 dimensional, AI?
