Sinful King
"Natalie Kane's Sinful King delivers a twisted, scorching-hot tale of love, obsession and feral devotion. It is dark and delicious, and features two distinctly likeable MMCs. What a way to start a series!" -- New York Times bestselling author L.J. Shen
"Their love is one for the ages and the spice... omg the spice is next level hot. There is banter, angst, and all the feels your heart desires. Brace yourself for one heck of an OTT protective and possessive MMC. I cannot wait to read the rest of the series!" -- USA Today bestselling author Michelle Heard
"When I say I devoured this book, I mean I became just as obsessed as the morally gray Mafia man did, which we know is saying something!" -- Bestselling author Neva Altaj
From NATALIE KANE, comes an all-new world with Sinful King, an age-gap, obsessed-hero, Mafia romance!
Eloise
I ran away from one organized crime household and found myself tripping right into another one. My father, the head of the Italian Mafia, is a bad man. He wants to marry me off to some creep I don’t know, but rather than succumb to that nightmare, I fled to Vegas, hoping to find a job and blend in. In the first week, I’ve been stolen from and beat up, and I have no money to my name, but I find a job as a bartender at RAPTURE, an upscale—okay, super bougie—adult club just off the Strip. I can’t believe my luck. I love this job, and I’m intrigued by the mysterious tattooed man with ice-blue eyes who always seems to be pinned to me. Things are looking up.
Until my father’s men find me.
Rome
I’m a ruthless, hard, dangerous man who takes care of his men and employees, and I run the city of Vegas with my brothers. That’s all I need. Until a gorgeous, raven-haired beauty comes walking into my club and sets my soul on fire.
I’m obsessed with her. Consumed by her. I need her in a way that I’ve never needed anyone or anything before, aside from the power and control that I’ve worked so hard for. She doesn’t know it, but I own the club that employs her, and I follow her back to the seedy motel she’s living in after her shift to make sure she’s safe. She’s mine.
Suddenly, someone is out to hurt my Firefly, and that means that they’ll meet a painful, bloody end. I’ll do whatever it takes to keep her safe. To keep her with me.
Forever.
"Sinful King was top tier and I could not put it down. Rome is an obsessed Mafia man who will do anything for the woman he loves. The way he cares for her through her trauma stole my heart." -- Eva Simmons
"There's nothing like a hardened, ruthless king who only shows his softer side for her. The way Rome was obsessed with Eloise had me hooked, but the way he cared for her through her trauma and showed up for her every time she needed him made me fall in love. The Kings of Mafia are my newest Mafia romance addiction!" -- USA Today bestselling author of Wolf.e, Paisley Hope

Review of advance copy received from Author
Well, this was quite the way to jump start Kristen Proby "after dark" as this new pen name is being touted as. Which I can get behind for sure! While this felt a bit uneven in tone at times, I am intrigued to see where she goes with these characters. I kind of felt like I was reading a book that would be found on the shelves of Billie's bookstore back in Montana, or like maybe her and Connor would take a vacation to Vegas and visit Rome's club sometime... but maybe that's just me.
Anyway, on to the review...
We dived right into a desperate situation for Eloise, when her father, who is in the Italian Mafia, is about to marry her off to a "bad man". She has been expecting this and has secretly been preparing to make a run for it. Knowing she'd never be allowed to get a real job she's been using her opportunity to go to school to learn skills she could turn into a career on the run. Meaning she's ready to apply for a job as a bartender? At a sex club. In Vegas. Okay.... Let's go!
Rome is the owner of said club, and is immediately hot for "Lulu" and when he overhears his club manager saying Eloise is too fat to bartend at his club, he nearly has a conniption. Good man! She gets hired on and the man who never lets anyone touch him, is ready to marry her in about 3 days.
Of course there's more to it. There's pressure from her father and the man she was promised to trying to find her. There's Rome's buddies being suspicious about her connection to the Mafia. Jealous bitches at the club, and plenty of BDSM goodness to keep us happy. But the pacing I describe is not far off. This book moved QUICK! There was not much time to breathe.
But I had a good time and I think it was a good start to the series. If you are new to Dark Romance and are following Kristen Proby from her other series, I don't think this will be too overwhelming, and that's probably most important. Though do mind the TWs, because it does have a few doozies spread through it.
Narrated by Teddy Hamilton and Avery Caris, and they were delightful.
4 Stars
3.5 on the Spice Scale
CW: parental abuse-from childhood through adulthood, loss of a parent (mentioned), BDSM elements, kidnapping, drugging, murder, and violence & torture on page.

unsafee
January 18, 2026note : he doesn't like being touched but has threesomes, is a manwhore and is very touchy and carressy with his employees who he also used to fuck
yeah that makes perfect sense
there's even a scene where he carried a naked worker away from a client who ignored her safe word, but how does he carry her you may ask? he carried her by the ass while she straddled his waist, but it's okay guys because the fmc was there😃😃 i get that it's because her back was hurt but the details could have easily been removed, we didn't need to know their position as he carried her

So this is the book LJ Shen & Michelle Heard keep recommending…
✅Age gap - 20 years
✅ shibari kink
✅ instant love/lust
✅damsel in distress
✅manwh0re/barely no experience heroine 🙄
✅curvy heroine 🥰
✅intense OTT MMC
✅touch her and ☠️
Small OW drama
🌶️🌶️🌶️ 🌋
Honestly, this book has a lot of good elements that I really enjoy in mafia romance (damaged damsel in distress, strong curvy heroine, morally gray hero, 🩸 🩸 …).
The writing style was good.
It’s quite dark (if torture is not your thing, look away)
I absolutely loved Eloise strong and sassy personality.
My main issue was with our MMC
- s3x club owner, to be honest the whole book is set at the club
- used to enjoy the occasional 3some, but doesn’t like being touched (not sure how it worked there) 🙄
- Used to f*** his employees (but he stopped now tyvm)
- Got jealous of the only guy Eloise was with before but it’s rubbed in our faces how many women he had in the past 🙄🙄
- The age gap was too important for my liking but I found out quite late in the book
-Spanked her when she told him she didn’t want to because she has been beaten enough in her past (but of course she liked it….)
Why, just why writers have to make the MMC a total manwh0re?? His past his rubbed in our face constantly, especially during sexy times!!
Quote “I have done it with a lot of women before….”
I don’t know if it’s supposed to underline how different Eloise is but it just doesn’t work… Dude you have sample the entire women population, so hard to believe she is THAT different!!
Despite he doesn’t like being touched he carried one of his employee, butt naked, off a scene that went wrong (yeah yeah I know it’s explained it’s s not s3xual, and Eloise agreed to it bla bla bla… but I don’t care !!!)he even kissed said employee of the forehead!
I am not touching Julian’ s book (has a scene with OW at the club, was married before and is pinning for his son’s fiancé )and Carson’s (dead lover trope), which is a shame because I love a good psycho!
So yes the book was enjoyable tbh. It’s a good mix of LJ Shen, Michelle Heard (obsessed at first sight vibe), Sadie Kincaid (past manwh0re) style.

Sinful King is a mafia, age gap romance between a high end adult club owner and a daughter of a mob boss. This book was a little different than I thought it would be, but I enjoyed it 😁 Lulu has suffered abuse from her father all of her life and has continued to overcome it. When she thinks it can’t get any worse, her father arranges a marriage to another cruel man and she decides enough is enough. She runs to Vegas under a new identity and stumbles upon a club while looking for a job. There she meets Rome and he decides she is THE ONE and will murder anyone that gets in the way of their love ❤️
I was so in love with the way Rome worshipped Lulu. He saw her and was immediately like, well she’s mine now 😂 She has low self esteem because she is a curvy girl, but Rome thinks she is the most beautiful woman he’s ever seen and makes her see the beauty in herself. It was so sweet! And he’d kill (and does kill) anyone that tries to harm her in any way. I loved that Lulu found a family that she needed between Rome and his men, and some of her coworkers at the club 🥰
The audiobook was duet narrated and was really good. The narrators fit their characters nicely! It was a spicy listen as well and had some scenes that were a little dark. So you might want to check out the trigger warnings before diving in, though it isn’t as bad as some other books I’ve listened to before.

Review of advance copy received from Author
"I don’t deserve one minute with you, but I’m going to take them all."
Rome is the definition of man obsessed, and saying I was here for it is a gross understatement. The number of times I wanted to be Eloise… Yeah, don’t ask.
"My hand balls into a fist on the desktop as a smile spreads over her perfect face, and even though I’ve never seen her before in my life, it’s as though every cell in my body recognizes her."
Eloise—Lulu—is in trouble. The daughter of a Mafia boss, she’s on the run after finding out her father wants to marry her off. When she finds herself in Las Vegas, with very little money and nowhere to go, she walks into Rapture, Roman’s club. Serendipitous, maybe? Or fate.
Whatever it is, the first time he sees her… He’s a goner.
"Where did you come from, my firefly? And why are you here in Vegas with so little when you deserve the world?"
She’s aware this is a sex club, but she wants nothing to do with that. No stranger to mixing drinks, she gets a bartending job. And she gets a very hot, very intriguing client, who looks dangerous but more than a little appealing.
She’s unaware he’s the boss and how much he studies her. How he sees the bruises she tries to hide.
And how he wants to give her the world.
"If I’m not careful, she’ll bring me to my knees."
Eloise is not one to let her guard down, but there’s something about Rome. Yes, he’s very morally gray, and she becomes aware of who he is and what he and the other Kings do, but, behind closed doors, the man is nothing if not swoony.
He’s the person she wasn’t aware she was looking for but now may not be able to let go of.
"Christ, there’s nothing about you that I don’t want. That I don’t crave. I lose myself in you, Eloise, and I don’t ever lose myself in anything."
I loved their dynamic. How he’s all in from the start and how it takes her a bit to catch up. To believe someone can be as crazy about her as he is. And, as a curvy girl myself, I could relate to so many of her thoughts!
"Forever. She’s staying for-fucking-ever. That’s what I mean when I say I’ll never let her leave."
I’m a sucker for a possessive, protective hero. From the moment Rome realizes she’s been hurt, she's his to protect. He will go to extremes to do it. No one will touch her again.
And, before you ask, yes, she’s just as possessive of him, and those “mine” moments had my heart beating faster.
And… If you’re wondering how hot they are? Oooh, get ready! It’s a mix of sexy, kinky—and with the right person, someone you trust, damn, it’s perfect!—and full of feeling.
"You’re the light that finally broke through the darkness of my black heart. You shine so bright, you made me feel human again. That’s why I call you my firefly. Because you flew right into my life and lit it up."
The obsessive, morally gray man pulls you into the story. The “meant to be” makes sure you stay. But it’s their love and devotion, the need to be close, the way they find their home in each other that had me falling in love with this book.
I can’t wait for more from the Kings of Vegas!

Available with all of my subscriptions
I’m pausing this… I’m a bit overwhelmed by everything, too insta lust, insta everything I don’t really feel the connection between the main couple… 😵💫will come back to it with a better mood
A few days ago I came back to finish this audio but some things still didn’t work for me…
I wasn’t going to post anything about it, since I felt like I was quite negative in some of my recent reviews - but the more the story progressed the more I discovered things that bothered me (so this is for my benefit if I ever want to revisit a book - I will have all the info) … besides the details about MMC’s hook ups in his smex club and having 🌳somes (although not liking to be touched!?🤔) and FMC having one experience 😵💫 but there were these constant emphasis on some stereotypes and reminders that the FMC was plus sized and the fact that everyone was reassuring her about her beauty regardless of her size!?- had the opposite effect- it didn’t feel empowering but self aware and doubtful…
in contrast some OW (Scarlet, I believe) from the club (with whom FMC became friends and MMC also carried naked 😵💫🫣) is described as a toned gorgeous blonde petite with larger breasts and she “caters more to those with dadsy kink!?” but is bisexual and per her words doesn’t discriminate when it comes to sex (but we are made aware that she quite likes Luke, sleeps with him only to have a rough sex scene a day after, with a different man😣)
The focus on certain aspects made me too anxious… bisexuality doesn’t = promiscuity, too much emphasis on body aspects and size will not always translate into a positive message…
The plot was condensed and rushed, also this also bothered me, the first time MCs do it, is bare, without any discussions about safety or STD only after it is done😳 Can we not!?🤦🏻♀️

I have loved everything I’ve read by Kristen Proby so when I saw her announcement of Natalie Kane as her “after dark” pen name I said hell yes, sign me up immediately. And as expected she did not disappoint, she actually exceeded my expectations. I am absolutely obsessed with Rome Alexander. There is just something about a “scary” morally gray man only being soft for his girl and boy oh boy is that true for this man.
The duet narration by Teddy Hamilton and Avery Caris was PHENOMENAL. I simply devoured Sinful King and left not a single crumb. So READ THIS! I already cannot wait for the next book!

I had a fantastic time reading Sinful King. It was entertaining, sexy, and intriguing. It was an exciting read with dark undertones, and I really enjoyed being introduced to this harsh world. Rome was intense, and I loved how he was instantly all in and wanted Eloise. Great start to a new series!
I thought Eloise and Rome were great characters. I felt for Eloise and all that she’d endured. Rome was intense and brutal, but the need and love he had for Eloise was everything. I liked Eloise gaining strength and moving forward in her life with him and how they forged an unbreakable bond. They have an instant attraction and a fast-paced relationship, but it worked for them. There was a big age gap between them, but I honestly didn’t feel like it was an issue.
There were a lot of characters introduced, and I’m looking forward to the stories about the other Kings. They are all their own brand of intensity and intrigued me. I liked the bonds the men had and how they were there for one another.
This story moved at a quick pace, and the details were good. I got just what I needed to stay invested in the story. There was a lot of drama, some not for the faint of heart. I loved Eloise and Rome’s connection and all the spice. Bring on book two!
Complimentary copy received.

I don't think I've ever read a mafia romance but I'm so glad I did! Talk about a man OBSESSED. Rome wanted Eloise from the moment he laid eyes on her. She was his no matter what. Eloise was running away from her dad, who is in the Italian mafia, when he was trying to marry her off. Rome was dedicated to protecting her no matter the cost. He's intense and broody and kinda scary but he was definitely soft for her.
I'm officially invested and can't wait to read more of this series!!!
🎧Audio🎧:
This is a duet narration by Teddy Hamilton & Avery Caris and they totally rocked it! The tension, the chemistry, the action, the spice... all absolute perfection!!
What to expect:
Dark Mafia Romance
Age Gap
No 3rd Act Break Up

I am 11 days into 2026 and this is my second new to me author of the year. Natalie Kane is another new author that I will definitely be reading more books from! Looking forward to Jillian and Natasha in Blood King next which releases.
In Sinful King we meet Rome and Eloise.
Eloise is on the run from her father, who is a bad man, And the head of the Italian Mafia. On top of him being verbally and physically abusive to her, she has just found out that he has sold to her off to be married. So she did what she’s been planning for and ran.
Rome is also a dangerous man, but he takes care of those close to him and that includes his employees.
Rome and his brothers run the city of Vegas. Vegas and my club Rapture are all that Rome thinks he needs. That is until he sees HER enter his club. When he sees her, he has no idea who she is, but claims her on the spot.
I loved how obsessed and protective Rome was of Eloise. Once he knew who she was and what all she had endured at her father’s hands. Rome knew her father was done for. I loved how their story ended and hope we see more from them in the next book.
Duet narration was performed by Avery Caris and Teddy Hamilton. As always, these two provided us with such a phenomenal performance of Rome and Eloise.
This story had me glued to the pages and my earphones from the start and I couldn’t listen fast enough. Amazing story and the side characters were all amazing too. I can’t wait to get Jillian and Natasha next.

Oh this was a bloody treat!! This is a dark, steamy mafia romance with Vegas vibes, obsession, danger, and that “I should stop listening but absolutely will not” energy. The story follows Eloise, who’s escaping a truly awful situation and basically rebuilding her life from scratch. She ends up working as a bartender in a Vegas club owned by Rome — rich, powerful, morally grey, and very much not the kind of man you casually flirt with and walk away from. Their chemistry is instant, intense, and just messy enough to keep things exciting. Rome is possessive, protective, and ruthless, while Eloise has this quiet strength that makes her really easy to root for. I loved watching her grow more confident while still staying true to herself. But honestly? The audiobook narration takes this story to another level.
Avery does SUCH an amazing job as Eloise — her voice feels warm, emotional, and real, and she captures both the vulnerability and the sass perfectly. You really feel everything Eloise is going through. And then there’s Teddy as Rome, who absolutely understood the assignment. His voice is deep, controlled, and dangerous in that calm, deadly way that fits a mafia MMC so well. Every line he delivered felt intentional and intense, and yeah… I may have replayed a few scenes. The duet-style narration made the listening experience super immersive, especially during the emotional and spicy moments. Definitely sticking with this series this is a MUST Listen.

Review of advance copy received from Author
Sinful King is the first book in the brand new Kings of Vegas series. It follows Rome and Eloise.
Right off the bat I was obsessed with this story. The mix of characters' personalities, storyline and the narrator's voices made this book a breeze to go through. I didn’t want to put it down as it was captivating, dark, heartfelt and dangerous.
Rome is the definition of morally grey but when it comes to his girl he is a complete cinnamon roll! He is extremely protective of Eloise from the first moment he sees her. Eloise is someone I would want to be friends with. She doesn’t put up with anyone's s*it, especially Rome’s and is so fierce. This was honestly such a great dark mafia romance and Natalie Kane (Kristen Proby) definitely hit it out of the park with this one.
This book was narrated by Teddy Hamilton and Avery Caris in duet style. I love both of these narrators and together they were utter perfection. Teddy really brought out both the dark and soft side of Rome while Avery brought out the vulnerability, pain and fierceness in Eloise.
I am obsessed with this series already and can’t wait for the next book!
You will enjoy this book if you like the following:
- Dark mafia
- Age gap (20 years)
- Obsessed hero
- Touch her and 💀
- Forced Proximity
- He’s Only Soft For Her
- He Helps Her Heal From Trauma
- Curvy FMC
Thank you so much, Natalie Kane, for the gifted copy!

Sinful King by Natalie Kane (audio)
When I heard that Kristen Proby was stepping into dark romance under her pen name Natalie Kane, I downloaded this on release day without hesitation and wow, did she deliver. Sinful King pulled me in immediately and had me completely hooked from start to finish. It was so much fun seeing this darker, more dangerous side of her writing!
This is an instant obsession, possessive mafia romance with a magnetic pull that’s impossible to resist. Lulu is such a strong, badass FMC who is confident, sharp and full of fire. I loved her from the very beginning. And Rome is just so swoony, dominant, unapologetically possessive and just the King of Sin City you want in a dark romance.
The audiobook narration was fantastic. Avery Caris brought Lulu to life with so much sass but also this deep vulnerability and fear from her past. And Teddy Hamilton… wow. I absolutely love him in darker roles and this performance was fantastic!!! His voice gave me chills and added such a commanding, magnetic presence to Rome that elevated the entire story.
This was an incredibly strong debut for Natalie Kane, and I cannot wait for more from this series. Kristen Proby After Dark is very much doing it for me.

I read this as a buddy read with Amy and Sarah, and I am so happy we did!! It was the perfect, cozy, dark romance book with some amazing spice! The book moved at a really fast pace which I enjoyed and I didn’t want to stop reading at our allotted chapters (I did stop, I was good haha) I really liked the set up of the world and I am excited to read the others in the series when they come out. There were some really heart-wrenching parts but also some really beautiful moments, it was just overall a really good read that gave all the feels.
Rome, our MMC, he was the perfectly obsessed MMC, all in on his women when he saw here and it made me giddy. I just love when MMCs are like this, and Rome was so perfect and swoony, I could have happily kept reading him and everything he did for Lulu. I really loved Romes' interactions with the other kings, too. I am so excited for their books!
Lulu, our FMC, was so sweet despite her harsh upbringing, I loved that it didn't harden her at all, there were so many relatable moments from her as well. I loved reading her fall in love with Rome but also loved seeing her friendship with Scarlett bloom as well. I really appreciated her being plus size as well, it always makes me feel seen reading books with FMCs like this.

I really don't have the words to say how much I love this book. It was perfection, no notes. I absolutely love how completely, from the very beginning, Rome is obsessed with Eloise. From the literal moment he laid eyes on her, he said "she is mine ". And in the next second I was on my knees for him. He does everything in his power to not only have her for himself, but to protect her and give her everything she could ever want. He's ready to literally burn down the world for her.
And Eloise, my girl, is such a badass. She is not a damsel in distress. Does she accept Rome's help? Absolutely. Does she feel safer and more content in Rome's arms? Definitely. But my girl can hold her own. She does not have a problem speaking her mind and saying what she wants. And when she does, Rome is more than happy to oblige.
These two are a match and gasoline. When they come together it is explosive. Like melt your Kindle hot!!
Every scene of them together is living rent-free in my head for the rest of eternity!
This book has been stuck in my head from the moment I started reading it. I cannot wait to do the audiobook, which I will be doing asap! And I am absolutely feral for the rest of this series! What an absolutely incredible debut by Natalie Kane!!
🌶️🌶️🌶️.5/5

Okay, I need a moment because this book was freaking amazing. From the very first page, everything just worked, the writing, the pacing, the characters, the mafia chaos, the emotions, the spice… literally no notes. I binged this in a single day and didn’t regret a single second. This is exactly what I want when I pick up a mafia romance.🙌🏼
Rome and Lulu? Absolute perfection. Brooding Rome is everything (except when he’s with our Lulu, because soft Rome hits different🥰), and Lulu… wow. That girl is strong, resilient and impossible not to love. Their dynamic, their growth, the way they balance each other, it all felt so satisfying and well done.
And can we talk about the side characters? Because they deserve their own moment, especially all the Kings and their banter! The Kings of Vegas completely stole my heart and now I’m sitting here desperately waiting for Julian’s book like it’s a personal need.😅
This was my first time reading Kristen’s work, but if her writing as Natalie is any indication, I already know I’ll be binge reading her entire backlist like my life depends on it. Mafia romance lovers, do not sleep on this one. 💥🔥

Rome is a powerful Vegas crime boss with very strong touch-her-and-die energy, zero tolerance for nonsense, and an alarming ability to be both irresistible and terrifying at the same time. He runs the city with his brothers, isn’t afraid to get his hands dirty. The second Eloise walks into his club, he is INSTANTLY obsessed.. I mean we do like a man who knows what he wants right? 😂
Eloise runs from one crime family straight into another and somehow manages to hold her own the entire time. She’s smart, capable, and refuses to be intimidated, which only makes the dynamic between them better. The chemistry is instant and the tension builds fast.
I listened to this as an ALC and the audio absolutely deserves the hype. Teddy Hamilton and Avery Caris understood the assignment and then some. Add in some mafia, forced proximity, alpha energy, and just enough brother appearances to make me impatient for the rest of the series and I devoured this. I finished obsessed, emotionally invested and already counting down for what comes next.

good read
I really liked the h/h. He fell so hard, so fast. Eloise was a strong woman and I loved the fact that there was no conflicts between the two of them. No 3rd act break up (I hate those) would definitely recommend this book. The other kings are interesting as well although their stories are not out yet.

This audio was so so good!
It's a duet narration with Teddy Hamilton and Avery Caris and they both delivered so well! It's been some time since I listened to Teddy!
The spice in this? Wowza! So good! And who doesn't love a man obsessed from the beginning, it was truly one look and he was done for. Loved it!!
Can't wait for the next book though cause the hints from this one?? EEK

I was lucky enough to receive an advanced audiobook and this did not disappoint! This book had everything I needed in a mafia romance. And the line, “Do you have a safe word” might be burned in my brain forever. So thrilled I got to listen to this one!
