There’s a moment in every girl’s life that defines her. I’m just not prepared for mine to happen at the altar, staring into a pair of intense brown eyes that will never belong to me, with mistletoe above my head, and twinkle lights glowing softly for our first kiss as man and wife.

Now he and his men want to claim me as their own. Want to put me on some pedestal and treat me like a princess, or at least their twisted version of one. Every look fires my blood. Every touch threatens to incinerate us all.

But I have secrets. One, they may be able to forgive. The other, well, it’s unforgivable. Once they find out what I’m hiding, there won’t be time for me to explain. My only hope is they’ll grant me mercy. Give me a head start. Let me disappear before they rain their own brand of justice down on all my lies. Because I’m definitely on the naughty list this year...Santa doesn’t even need to check his list twice. Ho, ho, f*cking, ho!

I've been trying to find a MC romance to satisfy a craving for over a week and nothing was working the way I wanted. Ms. Kelly's books are usually happily free of OW drama and a fellow reader confirmed there was none in Naughty Saint Nick, so I dove in. Now that the heart-thumping end has stopped for this ride, I can assuredly say that this book hit that sweet spot of what I needed and was just a fantastic read from start to finish. Bonus, it was a quicker and page-turning read too.

Remy is a FMC who's a survivor, a caring and giving soul in some situations, an ice queen in others, a badass, and so full of depths. She's distanced herself from the MC life she grew up in because of a past trauma and she gets roped back in through an unusual favor. The MC officers who she ends up with are protective, respectful, strong, and hot as all get out. There are some twists I don't want to give away in terms of what brings them together, but some of the relationships with Remy are already built and some are in progress still. There's insta-attraction though with more relationship development/deeper connection hopefully in future books since Ms. Kelly does this really well. While we get some background information on the guys, Remy doesn't know much about the new-to-her men yet and there's still the getting acquainted phase happening. This is multi-POV and I enjoyed being in all the characters' heads, with no favorites because they're all intriguing.

The content warning in the blurb is spot-on so please heed it if needed. Parts of the recollections of past trauma and the attempted trauma were difficult for me to read, but fit the story. There's also resolution which helped. I was not anticipating the source of some of the violence/torture in this series, which you learn about early on in the book, but I think it fit the character well and I can see a lot of readers liking that aspect (super vague). The other times balanced out the more violent parts well with humor, drama, and steam. Speaking of steam, this was a medium burn RH with no mm/ff. There was also a special something something involving one of the guys that's a "feature" I love to read about ;).

Book 1 ended on a lead-in to the next book with a bit of a reveal vs. a "characters in mortal danger" cliffy. I'm very excited for book 2 and this is my favorite start to one of Ms. Kelly's series yet.

Sin has officially done it again. This isn’t your average MC book. So whether you love MC or you think its not your thing, I’m shouting from the roof tops that you need this book in your life. Remy is a bad ass, and she’s put into an untenable position:switch spots with her sister whose in a pinch.

This all leads to twists turns, and the beginning of an incredible RH romance. I’m so excited to read more. I binge read this in 3 hours. You NEED it.

Hell yes!
Bloodthirsty FMCs are my absolute favorite!
I loved this.
I’m really hoping that she keeps up with that same energy in the rest of the series, because holy crap.
This was exactly what I wanted to dig into right now.

Wow wow wow 🤩

Such a good storyline!!
Remy has become her own avenging angel since leaving her fathers MC and that life as far behind her as possible after an awful life changing tragedy 😣
…..until her twin sister asks her a blond favour!
Suddenly finding herself thrust back into MC life, not as herself, she begins to question all of what she knew about how they operated!
The Sinners MC have an automatic connection with Remy albeit unknowingly - cannot wait to see how they all respond after that bombshell discovery 😍
Preordered the next one straight away (although I NEED it now!)

ehhhh it's alright??? Lots of potential, truly, and I like the characters, but I feel like I barely got to spend time with them or learn anything. Also, how could they not find time for a meeting and get rid of the guy before everything went down???

So... idk I might read the next.

I’m in love! I haven’t read an MC book in awhile and this story reminded me how much I love and miss them! Remy is a character I instantly liked. She’s like a vigilante and doesn’t take anyone’s crap. The plot of the story completely pulled me in and I couldn’t put the book down. It went entirely too quickly and I’m dying for the next book! I can’t wait to see what happens and to get more of Remy and these men!

This book was freaking EPIC! I reached the end way to soon, I never wanted the words to stop. It only took meeting each of these characters for me to fall deeply in love with them. Remy is one of my all-time favorite heroines to date! She is strong, determined, intelligent, loyal, and above all else…a survivor. Remy is the epitome of strength, willpower, and resilience. I am in complete awe of her. And let’s me honest, I totally want her to teach me some of her killer skills!

Ace, Saint, Trip, Rogue and Squire have completely consumed me mind body and soul. I love that despite the reputation MCs get, they are genuinely good men. They care for Remy and want to protect her at all costs. Definitely doesn’t hurt that they are sinfully sexy to boot.

This story was full of action, mystery, suspense, passion, stabby times and so much more! I never wanted this story to end and I am biting at the bit for the next book. I have grown so attached to these characters in such a short amount of time…I’m caught hook, line, and sinker. An absolute MUST READ!

Outstanding!

I’ve been in a bit of a rut recently. Books were good but I wasn’t captivated by their plots. Not like the way this book pulled me in.

I love a strong FMC and Remy is just that - she has a devastating past but pulled strength from it rather than letting it ruin her life (it wasn’t an instantaneous journey and she is still in the process of healing).

In a case of hidden identity, she has taken the place of her twin in an arranged marriage to secure the future of two MCs.

We get age gaps, friends to lovers, secrets, and revelations.

It’s a medium burn and steamy building why choose relationship.

This ends in a bit of a cliffhanger and luckily the next book is available so I can dive right in!

Such a good first book in a series. I highly recommend jumping right in.

Downloaded a bunch of books to my Kindle and then clicked around blindly, without reading the blurb but thinking this was another collection of short christmas stories I've been ticking off my TBR this month.

It was not. And I seriously could not be happier to know that the story will be expanding further than what I initially thought would only be 100ish.

So, first things first. I love the FMC, Remy. She's strong but also a little psycho. I'm glad that so far she has been able to work through the whack-a-mole style obstacles that she's faced with 0% warning they're coming at all and still maintained both her mask and her strength.

Her sister, Etta, is getting coal for Christmas. I'm sure once we finally find out exactly what caused her to leave Remy in such a weird predicament, even though said predicament is going to turn out to lead Remy to her happy ending (I hope), I'll be more understanding. Still, right now? Coal.

With the tiny bits of information we get regarding the rat in the henhouse situation over at the Reapers HQ, we still basically have no idea what's going on and who is involved except for 1 mothertrucker. Who, thankfully, quickly and spectacularly met his end.

The dudes. I don't feel like I really know all that much about them other than they're all down to pound...Remy. 😅 It seems like Remy's backstory and...hobby...was the highlight of this book with small pieces of the men, their feelings and history. It's only book 1 so I am 100% accepting of this and not complaining about the way it's written at all.

The volunteer who stepped up at the end of the book to join Remy and Squire in their side job had me a little surprised. While there is a 0% chance of a cliffy induced heart attack, I am more than excited to read the next book.

Things probably no one cares about:
📌Multi-POV
📌No MM (not sure if this will be true in future books)

This series is gonna be EPIC!!!

Remington, or Remy as she likes to be called, has distanced herself from her families MC, the Havoc Reapers. She is happy working in the hospital, spending time with her BFF Squire, and staying away, until one night Saint from a rival club comes into the hospital dressed as Santa. They have a moment and she can't stop thinking about him. A week later, she gets a call from her sister Etta, to do a twin switcheroo, so Etta can get away. Remy agrees to pretend to be her but only for a few days. When she goes to the clubhouse as Etta, she is not expecting to be married off.

Sinners Mark MC is a rival club to the Havoc Reapers. Ace is the president, Trip is VP, Saint is secretary, and Rouge is Sergeant at Arms. They are a more legit MC than a one percenter. Saint has been head over heels for Remy since he was 17, and they all know it. The Havoc Reapers want to join forces with Sinners Mark, by having Ace marry Etta. The guys have always wanted to find an old lady to share, but they don't really want Etta.

Remy has been through a lot, and has worked so hard to get past those things, with her best friend Squires help. He wants to be more than friends, but the marriage kinda thru a wrench in his plans. Remy isn't what she seems and I love it so freaking much!!

I loved this book!! Sinclair Kelly is just magic when it comes to writing RHs that pull you in and keep you turning pages. I love everything Sinclair writes and I know this series is gonna be AMAZING! Read this book as soon as it comes out!!!

Great Start To New Series!!

Wow!! This book isn’t for the faint of heart but its what I love best in MC romances. Remy was amazing in this story because she survived an unthinkable event that eventually led her to a path of being a vigilante who took out the vilest of humans. She was strong, sexy and smart and she even was a volunteer at a hospital. Oh, yeah and her dad was the Prez of a rival club of the Sinners Mark MC who Saint was a highly ranking member of. Saint knew what he wanted and that was Remy.

Oh boy, do things take off from there because Remy’s twin sister, Etta, sets her up and finds out when they switched spots that she would be walking down the aisle to marry the Prez of the Sinners Mark MC, Ace, with no one knowing who she really was. One of the first things Ace told her was that he and his top-ranking brothers and guys he grew up with, including Saint, like to share…only with her permission.

There were so many things happening in this book that I couldn’t put it down because it drew me in from the start and didn’t let go until the last page was turned. This book had it all from the connection from the men and Remy, betrayal, drama and all the craziness going on in Remy’s mind.

I highly recommend this book and I can’t wait to get started on Rogue’s story!!

I have been tricked! Hoodwinked! Bamboozled!

You know how they say to never judge a book by its cover? Can't be truer for this one. Sinclair Kelly has now given me severe trust issues. Will I ever trust her again? The jury is out, folks. But let me present my case anyway:

Look at this cover. Take a good, hard look at it. Guess what I was expecting? That's right. A Christmas book. With a hot tattooed alpha and spicy scenes that would make me run out of batteries. Maybe he'd be an ass, and her goodness would make him fall in love under the mistletoe. There would definitely be a roaring fire and fairy lights.

Now, I'll admit...I went in blind, without reading the blurb, so that's on me.

BUT, COME ON!!! Christmas!!!

Instead, we get blood. Lots of blood. And revenge. And a reverse harem MC! We get mystery and evil and a kick ass FMC.

Sin has gone dark, and I'm here for it!

Could hardly put this down, and my "NOOOOOO" when I realised I'm going to have to wait for the rest could surely be heard all the way across the pond. (Sorry if I woke you, Sinclair.)

So, if you're looking for a not so Christmassy MC book that's going to leave you desperate for more...check this one out!

Oh, and Sin...you owe me for therapy appointments to work on these trust issues! 😆❤❤

The Avenging Angel

I was not ready for this book!

First off the prologue starts off and I’m like “ehhhh, no grown man would talk like this…” but I heard it was super good so I continued on. O M G… I’m so glad I did. It was amazing! It def took a turn I was not expecting and I AM HERE FOR IT! Things definitely weren’t as they seemed.

Parent trap meets hot sexy alpha motorcycle club!

Remington is a force to be reckoned with. With Ace, Saint, Trip, Rogue and Grant I cannot wait to see how this goes. Remington does a favor for her sister with no information and she soon finds herself in over her head.
When the Reapers are in need of the Sinners help but theirs clearly a rat amongst the ranks, does she have what it takes to make things right? Can she go through with this task with her dark history?
Book 1 ended on a crazy cliffhanger and I already preordered book 2!

“…I may be small, but my bite is deadly. Guess it’s time these guys learn that.”

So good!!

*Overall 5/5
*Slow Burn
*Heat? 4/5
*RH (No MM)
*HEA? Yes and no. Lol

This book is the very definition of don't judge a book by its cover. I mean, it's a great cover, but it doesn't tell the whole story of what's to be expected within the pages of the book. If you're expecting a naughty Christmas story...well, you'll definitely get a hint of that, but you'll also get so much more! The FMC has a dark past that has led her to an even darker present- one she takes pride in. The MMC's are all dreamy Alpha males that are as tender as they are terrifying. There are triggers of sexual assault, so be warned. But if you like feisty, sassy, take-no-shit FMCs and the men that love a challenge, then this is the book for you!
Don't forget to check out Sinclair Kelly's other books, they are equally amazing!

Naughty Saint Nick will melt your panties!! Despite the fact that our FMC, Remy; is incredibly reserved and teetering on the edge of what she describes as the last of her humanity, she finds herself surrounded by a group of sexy men who want nothing more then to take care of her. Even if they don't necessarily know who she is (in more ways then one). I loved getting to know Remy and the guys. Remy has been through so much and she really needs her men in order to move forward in her life because she had ultimately accepted the fact that she was either going to die early or end up in jail. Only these guys and their support are able to turn her around. Incredible read!

I'm having a hard time explaining how much I loved it, it's full of secrets, dark events and a twist that I never even imagined happening.

It was sexy, cruel, dark and completely perfect, I flipped through the pages like a drug, the word flowed and I didn't want them to end... the book is definitely on Santa's naughty list, we saw passion, growth and alpha males, with family love, sacrifice and violence, which all blended perfectly.

A strong leading lady, with a swoon-worthy best friend, MC drama and with many bad guys, flashback moments and good-old-revenge.

I really would like more, I need to know what will happen next because the book was over far too soon.

XOXO Lottie.

I absolutely loved the first book in the series. Mindfu*k meets RH and MC... what could be better? I completely fell in love with the characters and the world Ms. Kelly is building. Is it strong on the whole Christmas thing? Not really, a mention here and there, but still a fantastic, mind blowing first read and I can't wait for the second.

The details:

No m/m as of yet (kinda hoping that that continues)
Kicka$$ fmc that is soft and vulnerable, but can kicka$$ and take names when she needs to
MC guys that are all Alpha, but also sweet towards their girl
A childhood best friend?!? Who doesn't love that idea!
Mfmmmm

I have to start this by saying I love the titles of the books and how they incorporate the names of Remy's guys. I was totally not expecting this book to turn out like it did and I cannot be happier with the way that this story is heading. Also for those who do not like cliffhangers I would say that this book ends in a diet cliffhanger, many things are left unresolved but there is not a huge twist that guts you at the end. I am so excited to see what happens next for Remy and her guys and I am hoping to hear more about Etta and what is happening with her.

I dare anyone who reads this not to be completely blown away! I’m so in love with this entire harem… There are two of these guys I feel like I know least, though I can’t wait to get to know them all better. I would be shocked if readers didn’t fall in love with all of them by the end though I have three favorites at the moment now. Why choose, right? Sinclair shines with this one by giving us Remy, though. She’s a total package as an FMC. She’s been through the wringer and found a way to make her broken pieces part of her resurrection. I can’t wait for more now that we’ve started on this amazing journey with Remy and her men!

I received an ARC for an honest review.

I just want to say I’m so glad I was able to read this. I haven’t read too many MC books, this one blew me away though. I couldn’t put it down. Remy is the badass I think all RH female characters need to be. With all the alphas surrounding her, she can hold her ground and then some. I’m looking forward to the next book. With secrets revealed, I need you know what happens next!

Yes, yes, and yes please. I need more. What doesn’t this book have except for everything. Bikers, a sassy, fantastic, amazing female lead, and did I say hot bikers, if not there’s hot bikers. Also, can we say I think we all need Saint Nick in our lives. Can’t wait for the next book and how this story goes.

Loved this and need more!
Remy kept me on my toes from the very beginning. I love everything about her character, she is an incredibly strong women that was knocked down far to early in life but she came back swinging.
Saint might me my favorite of her men but Squire and Rouge are a close second.
I was so engrossed in this story I read it in one sitting.

I’m not a huge MC fan so I was nervous about reading it but I’m glad I gave it a chance. I really enjoyed this book. Also there is one bada$$ B in and I’m obsessed with her. I’m looking forward to learning more about the guys because you really only get in depth with two of them.

I’m face I started it at 1130 at night while waiting for another book to release and couldn’t put it down! I will definitely be rereading this when I need to get myself out of a slump!

This medium burn, MC reverse harem is sure to warm you up this holiday season. Naughty Saint Nick is all things naughty and nice.

Remy is a survivor, a fighter, and a vigilante of sorts. When her twin asks for a favor, little did Remy know the chaos it would bring. Finding herself surrounded by sexy as sin men complicates things, but the closer she becomes to them

It’s freaking fantastic and the end of it came waaay too soon. Sinclair Kelly is amazing at writing reverse harems and this one is no different. I loved everything about this book and I can’t wait for the next.
