This dark romance featuring Nikolai and Sienna had a promising start, but it quickly lost its way for me. I struggled to understand the main character's obsession with the female lead; it felt unearned and abrupt. The story mentions that Nikolai followed Sienna for three months, which could have been a great opportunity to explore the gradual development of his fixation. Instead, he kidnaps her to get her friend's attention, and despite her hatred for him, they end up having sex early on, around the 20% mark. This felt completely off, lacking any real chemistry or buildup, making the whole situation seem random and forced.

4.5✨ Okay, this was an ALL-AROUND YES for me. I had such a fucking good time with this book.

Sienna is an actress/model basically living the life everyone expects her to live. She’s the spoiled princess, the pretty girl, the woman who is supposed to sit there and look good, but underneath all of that, she’s unsure. She’s been through pain and betrayal, she’s insecure about a lot of things, and she’s carrying way more quietly than the people around her realize.

So when she gets kidnapped because her best friends husbands are involved in the mafia and she’s taken as leverage, she is understandably like… what the actual fuck is happening?!🫪

Especially because she has NO idea the people closest to her have ties to the mafia. She feels betrayed, foolish, and completely isolated because everyone has been keeping this huge part of their lives from her. And I really loved watching her start to realize that maybe she wasn’t actually living before all of this. She’s spent so much of her life being who everyone expects her to be, and this experience forces her to figure out what SHE actually wants, even when those things aren’t exactly conventional.

I love a self-discovery journey.

And then there’s Nikolai.🥵

Six-foot-seven. Tatted. Scar on his face. Ruthless as fucking hell. (RAW)

His nickname literally means boa constrictor because his favorite way to take a life is by strangling someone and watching the life drain out of them. Yeah. This man is not to be fucked with.

But what I loved about Nikolai is that he’s actually a character. This is exactly how you do a cold, calculated mafia man because he can be absolutely terrifying without being completely devoid of personality. And I’ll say it a million times: BANTER in a mafia romance is so fucking important to me, especially when you’re giving me kidnapping and Stockholm syndrome. I need these people to have personalities or I simply do not care.

And Sienna has the personality BABY💅🏻

Because not this man kidnapping her and then telling her to “mind your manners.”

LMAO Y’ALL SNATCHED ME UP???

She gives him nothing but fucking hell and sass, and honestly, I feel like her reactions were probably exactly how I would react.

Like, “Okay, what the fuck is going on? I’m freaking the fuck out.” But then she looks around and realizes she’s being treated like a fucking princess.

Because this man is a THOUGHTFUL kidnapper.

He sets up her room exactly how she likes it because he’s been stalking her for three months. Even her skincare routine is accounted for.

This is luxury kidnapping.

A high-end hostage, if you will.

Every day there are fresh flowers and fruit beside her bed. He brings her favorite meals, chocolate chip cookies, red licorice… he is literally shopping for her and making sure she has everything she likes. His attention to detail was literally immaculate, it’s probably from the stalking though hehe whatever it’s romantic.

Are we sure she’s being kidnapped??? Most men in loving committed relationships don’t even do this shit😂😅

This man literally kills her stalkers and then decided to stalk her himself. LMAO. He knows the way to her heart. And somehow, despite being a literal ruthless killer, this man is also the KING of acts of service.

He unbuckles her heels for her.

He brings her favorite things.

He does fucking pinky promises. PINKY PROMISES🫠

The big, bad mafia man doing pinky promises does something to me. Listen, he might put you in a cage and drop you in a shark tank, but at least he’s in the cage with you. Then he’s gonna turn around and teach you how to throw knives at your cheating douchebag ex.

It’s all about balance…..

He’s crazy. And Sienna is basically like, “Yeah, fuck it, whatever.” It’s got to be the scar that got her, same girl. I love that she’s constantly getting this man to bend to her will, he’s for sure the one in charge, but I honestly forgot that a few times with how he kept meeting all of her demands.

Then the lines between prisoner and lover start blurring pretty quickly, and honestly, can we blame him? He’s been stalking her for months and has obviously gotten a little attached. It’s giving soft spot. Its giving lover boy.🤭

And the spice in this book was SO fucking hot.

We really thought outside the box with this one, and I’m here for it every time. Every time this man used an inanimate object, I was like, “Huh?!”

And then two seconds later:

“Okay, yeah.”🥵

This man gets her off with the spine of a fucking book.He uses his bracelet like a personal set of anal beads. Freaky. I like it. This book really said “let’s just see how far we can take this” and I respect the commitment.
(🦈🐍🐅👀)

The plot also had enough OH SHIT moments to keep me excited and addicted without going so overboard that it distracted from the actual story or romance.

And now I’m fully invested in the rest of the series because I NEED to know what is going on with these other couples and families. I’m assuming the friends have their own books, and after this one, I absolutely want to go back and read them because there are already characters who have my interest fully fucking peaked.

Overall, I loved the characters, the romance, the banter, the mafia plot, the spice, the self-discovery, and all of the completely unhinged shit that made this book feel a little different from your typical mafia romance.

Maybe it's my bad because this is like book 5 in an inter connected series and I didn't read any of the previous but I'm so serious when I say all of the characters in this book could have died and I wouldn't care at all.

I couldn't really connect with the characters, I didn't vibe with the romance and frankly I was bored to indifference.

I definitively missed out on lore because the way they kept dropping in and mentioning characters like I was supposed to know them was baffling.

I understand why people could love it but that's not me, I'm not people.

I tried!! 😭 I hate dnfing books but this just did not hit. Of all the Mafia books I have read this was so weak.

There was nooo build up, nothing. Hate to smut at 20%? From nowhere. He was obsessed from the start without explanation. Like there was a mentioning that the mmc had followed the fmc for three months. Why not use that to write how he slowly became obsessed and why. But nothing. It was even dual pov which could've been perfect to write how he followed, thinks he started to like.
He just kidnapped her to get her friends attention after orderes from the boss, then she hates him but still they have s*x at 20% ish. It didnt feel right at all, random and not a build up of chemistry at all.


The mmc is like 36 going on teen, the fmc is 29? And still is like a little lost puppy. Usually the over bearing, obsessed mmc in Mafia romances just hit but this was poorly executed. It was like the author has seen what people liked on booktok and tried to make everything happen at once. In addition to that the plot was very weak, I just don't know what needs to happen at 50% for the book to continue.
Not much was likeable in this story, not the writing, characters or plot. So unnecessarily long too...

DNF at 53%.

The only acceptable reason I made it halfway through this book is probably because I was in the mood to read a trashy mafia book. But then I was like… why am I doing this to myself? 😭

Both main characters were insufferable. They were acting like teenagers, and I seriously couldn’t handle it anymore.

The FMC was a brat who tried to act tough, but she just sounded like a spoiled teenager.

The MMC is 30+ and was acting like a 15-year-old boy So fucking annoying.

Not really a review - just notes for myself.

MFC was horribly immature and annoying.
Just another average mafia romance.
Not a series I would continue personally.
Shark scene was comical and ridiculous.
This was a TikTok recommendation. I need to stop listening to those recommendations.

So this book was a breath of fresh air compared to the other books of this series that I’ve read. I enjoyed the storyline and the character development. The spicy scenes were a little lack luster but if you’re looking for more plot than spice this book is for you

This could’ve been so much more fun and interesting, but sadly the plot just didn’t keep me invested. The whole “capture her and keep her hostage just to lure her friends in” storyline didn’t work for me, especially when she has nothing to do with any of it.
And enemies to hate-lovers by 25%? Way too fast for me. I need way more angst, tension and build-up in a mafia romance, and this just felt too rushed. Sadly, neither of the main characters was particularly memorable to me either. Overall, just not the book for me.

“Careful, mishka, I quite enjoy my women feisty.”

Her captor uses an ice cube and the spine of a book to get her off!!!! Enough said 🙌🏻
After reading this, it’s made me want to go and re-read the previous books.
This is one of my favourite Mafia Series and I will always recommend these to people.

I highly recommend to read in order starting with Insidious obsession.

I loved this book so much! ❤️

The story starts with Sienna, our 6'ft model,actor and spoiled princess who goes to a club to forget about her cheating ex. But instead, she ends up getting kidnapped by our MMC, Nikolai—a 6'7" man with a scarred face and a tattooed body.
Nikolai kidnaps her as leverage because her friend’s husband is involved in the mafia. Sienna has no idea about her friend’s mafia life, but now she finds herself being kept at Nikolai’s estate.

Their chemistry is AMAZING, and they can’t deny the attraction between them. I absolutely loved watching their relationship develop and seeing how beautifully their love blossomed. ❤️

Definitely a book I enjoyed so much!

She is a model/Influencer from a rich as fuck family. Used to the best.
She has a wonderful group of friends she trusts above all. A wonderful fiancee.
Then it all implodes.
Her fiance cheats… Gets another woman pregnant. She leaves him.
She is abducted and held hostage.
Her friends doesn't even know she is missing…
Money won't fix this.

Udav/ Nikolai, the Russian Crime Lord with more secrets than Wonderland, is the one tasked to Stalk and take Serena.

She is his captive but does she stay just his Captive…. Their chemistry is off the charts and she cracks him open one cheeky non submissive note after the other but all she wants really is someone who sees her, dominates and guides. A Safe place to land..

Not too much to ask is it.. From your kidnapper?

Also… Did I mention the end for them was written already , she is a hostage not an end game.

Mafia , Romance, Action , Spice and LUVING…
(little twisted since it 's dark romance with morally grey men ;) )

The fifth book of the insidious obsession series is here and this book follows our darling Sienna. The books in this series are interconnected standalone’s but there are some previous plot lines mentioned in this book, just to be aware.

If you’ve been following along in the series you will remember that Sienna was off the market because she was dating an actor only to realise he had been cheating on her. Now that her friends have all found their other halves she decided to take some time for herself and jet off to London. It is one evening that she is in fact snatched by a man named Nikolai and the reason Sienna was taken was due to her association with Luca Armani and Ara Barone, who is Sienna’s best friend.

After the fall of the Lion in NYC the Wolf, who Nikolai is reluctantly assisting, is trying to claim that power and by Nikolai taking Sienna it is only a stepping stone in doing so. Nikolai did his research on Sienna for quite a few months to gather his intel and you cannot tell me this man did not fall for her during that time as this man hadn’t even met her yet also ‘took care’ of a few of her followers that were a bit too forward.

Sienna is fierce but she definitely keeps her problems buried beneath the surface. Sienna struggles with infertility and longs to be a mother so the fact that her ex not only cheated but is also expecting a child with the woman he cheated with impacted her greatly. Sienna is not a woman to bend and she certainly does not make it easy for Nikolai and I mean why would she?

As we dive deeper into the book the pair start to understand one another and we see the tension start to brew. Something that shouldn’t have been temporary no long is. Nikolai is possessive and that’s just how I like my MMCs and we definitely see how devoted he is to Sienna even at the hands of people he considers enemies, he will stand by her side always. There is nothing sweeter than when you fall for the person who should have been your key to revenge, also through in the forbidden aspect of falling for a man you most certainly shouldn’t? Yeah I absolutely LOVED it.

Overall I absolutely loved Nikolai and Sienna’s story, quite a few twists as well that had me hooked. Thank you to the author who provided this e-arc for my honest thoughts 💭

(4.5) I forgot how quickly the author jumps right into the story, I love it though. This book was good, and I don’t usually like captor/captive tropes, but I didn’t dislike this one (probably because it wasn’t as prevalent and Nikolai never acted like he hated her). I loved that there was a balance between the two POVs, and they were cute together. But, I so badly wanted to rate this book higher, because it was good, but there was just something missing…or lacking? IDK. I think if I read this immediately after book 4 I’d enjoy it more, but because it’s been some time and I’ve read other mafia & captive/captor books it just, unfortunately, didn’t hit the same :( But it was still good!!!

Captured in the best way!

Went back and reread the whole series before this one dropped, and it was so worth it. Sienna's spitfire energy never dims even when she's kidnapped, and Nikolai's possessive, watchful obsession over her — down to knowing her favorite meals — is everything I want from a captor x captive romance. The way their relationship builds and eventually combusts is so satisfying, and he was willing to give up everything, even his own life, just to be with her when the chance finally came. Five books in and I'm somehow more obsessed than I was in book 1. If you love forced proximity, possessive MMCs, and a hero who falls first, this one delivers.

Highly recommended!

This is definitely a must-read! I loved how soft he was for her and how he protected her from the very beginning. The suspense kept me hooked, and I couldn't stop turning the pages. I also loved that he was willing to betray his boss for her, which made their relationship even more intense. Their chemistry was undeniable, and they just couldn't keep their hands off each other. I had so much fun reading this book from start to finish. It was thrilling, emotional, and incredibly addictive. Highly recommended!

Here we get Sienna's story, she's taken herself of to London after a messy breakup but unbeknownst to her, enemies of her best friends husbands (their stories are in the previous ones to this) see her as the perfect leverage to do them damage....

She's feisty and completely oblivious to the underworld and he thrives in it.

For me, Captured Obsession is the kind of novel that sets the bar of love at its highest!
Let's talk about Nikolai, our MMC. He’s 6’7 in height and has a gorgeous aura! He’s strong, instinctive, strategic and yet very possessive of his women, both Sienna and Agatha (mother like). And his nickname is Udav, it’s his way of killing people that gave him this title. I wish they describe more of Nikolai’s future….

Now it’s time to recall our hot and fierce FMC Sienna Falcon. Her nature is her strength, although physically, she’s strong and her height is 6 feet! She’s a fabulous model, friend and daughter as well. The fight in her soul is remarkable because maybe a normal woman might have lost her mind when she got to know she’s been kidnapped and her bf is engaged and going to become a father soon… Sienna is my one of the favorite FMCs❤️

The way she protects Nikolai and also remembers how he protected her first, and now it's her time to protect him because he never asked her or even manipulated her to protect him, so it feels like she really loved him that deeply. I also liked Sienna's father and the way he was concerned. I felt this story was a little incomplete because she couldn't get pregnant and we never got to know the reason but what so ever It’s their journey and we lived it with them and loved it too! ❤️

From the moment I read the blurb, I had a feeling I was going to love this book, and I absolutely did. The whole setup leading up to the excursion was so well done and had me hooked. I really enjoyed watching Sienna slowly discover the truth about her friends and seeing how she handled everything once she realised what was actually going on. And Udav protecting her from the very beginning? Loved that.

Also, the moment Dimitri Volkov was mentioned, I immediately knew there had to be some kind of connection between him, Udav, and his wife. And guess what? I WAS RIGHT. 😂 I love when my little theories actually turn out to be true.

This book had everything I wanted, and I genuinely loved reading it. 🥹

My ranking:

1. Fractured Obsession
2. Captured Obsession
3. The Insidious Obsession
4. Unruly Obsession
5. Carnal Obsession

Intense, Dramatic, and Full of Twists!

Captured Obsession took me on a ride. It has captor/captive romance, forced proximity, mafia themes, and so much more.

The story follows Sienna, who is captured because of her connection to her friends and becomes a pawn in a bigger situation involving their husbands.

Nikolai was so protective of Sienna, even when he didn’t have to be. From the moment he claimed her, it was clear he knew there was no going back, and I loved seeing how his feelings developed.

One thing that frustrated me was Sienna’s friends keeping their connections to the underworld from her. It made Sienna seem unaware of things she deserved to know.

I also loved how Sienna’s father quietly fought for her, especially when it came to standing up against her cheating ex.

Kia definitely didn’t disappoint with Sienna’s story.

This is a 4-star read, and I recommend it.

Accustomed to the finer things and living in the spotlight, Sirenna got kidnapped as a pawn. Her captor? She'd never even heard of him—wasn't like she'd grown up in the underworld or anything. Yeah, some people would probably call it Stockholm syndrome. Though here's the thing: during those months locked up, she had this weird realization. Life had always been handed to her on a silver platter. Then she started spending time with Nikkei and learning about all the rough stuff he'd dealt with growing up. What really hit her, though, was finding out that her entire friend group had been keeping this same secret from her the whole time. That's when it clicked—they just didn't think she could handle that side of their lives.

Turns out, the two of them kind of completed each other. Her friends had gone through way tougher situations back when they were getting together with their husbands.

Waitttt this was such a good mafia romance!!! I loved how the FMC was such a spoilt baddie from the beginning- make his pockets hurt!!! She was also just a baddie I really liked her. The MMC was kinda mean but not really and he was always down back for the FMC which you have to love. There was good plot and good banter. Just a solid mafia romance.

Spice was totally there... and who doesn't love a Strong, Hardened, Tall, Muscular Man, who's cold, hard heart softened by a Strong Women!? (Seriously who?)
Or does he? 🤐 ? I can't give it away, so you gotta read it to find out!

It wasn’t bad but it wasn’t that good either. It was missing a lot of connections & nikoli’s dialogues were just poorly executed. I wanted to feel his emotions but meh. Overall the book was missing emotions.
