Loved It
Now that the badge is off Katie is working to bring down a child trafficking ring and do what needs being done. When she is led to the Steel Saints MC where Dalton and Mac are members she finds more than just information. When the time comes will she be able to make the hard decision.
I loved this MC book with the drama, action and steam and look forward to reading more from this author.

You had me at motorcycle club and why choose. Then you added that they’re brothers... truly the gift that keeps on giving.
I listened to this on audio, and while I wish the male narrator, Jimmy Alli, had more page time, Rachel absolutely kills this audiobook. She did a fantastic job voicing multiple characters and keeping everything engaging.
Our FMC, Katie, is a detective working a case involving missing children. When she’s given the chance to go undercover and infiltrate a biker club, she jumps at it, and honestly, she was made for this role. The moment she walks into the biker bar, she makes quite the impression. After a small fumble, she ends up on the inside as the club’s new live-in maid.
Our MMCs, Dalton (the golden retriever type) and Maverick / Mac (the darker, brooding brother), help run the club, and once feelings start developing, things get complicated fast.
The pacing and plot were solid. I really appreciate a why choose that doesn’t spend all its time in the spice department and actually delivers a decent, engaging story. For a debut, Sarah K. Mason did a great job walking that line.
This book has suspense, action, spice, and a strong plot. A few things fell a little short, but overall this was a great read... or honestly, if audiobooks are your thing, this one is excellent.
A solid 4 stars, and I can’t wait to read more from Sarah. Keep them coming.

This book sucks you in from the very beginning and keeps you entertained until the end. I loved the FMC and the MMCs. I laughed, gasped and read until I couldn't keep my eyelids open.
The main character, Katie McGrady (Nicole Moore) is a badass and never let's anyone or anything get her down for too long. The MMCs were morally grey for all the right reasons and I really liked the connection they made with Katie throughout the book.
I received an ARC for this book and I'm so glad I did. I was scared at first because I've been having such bad luck with ARCs lately, I've felt like I have been cursed. This book really turned it around.
If you like badass FMC, swoon-worthy MC MMCs, action, heart with the right amount of funny, you'll love this book.

I’m not usually a why choose girl. I like my men unhinged in the possessive department — the “that’s mine” growl, the won’t-share, will-☠️-a-man-for-breathing-too-close type. That’s just my personal preference.
But let me tell you… this book? Top. Tier.
Shoutout to Hollie for the recommendation because wow. I don’t even read a lot of MC romances, but I am SO glad I gave this one a shot.
You’ve got Dalton — the fun-loving one. Charismatic, easier with a smile, but trust doesn’t come naturally to him. He guards it carefully.
Then there’s Mac — Maverick — and whew. That man does not trust. Period. His walls have walls. So when he lets them crack? When he chooses to let someone in? It’s powerful. It’s beautiful. It means something.
And then there’s Katie… Nikki… whichever name she’s using at the time. An undercover cop walking straight into danger. She’s not there for love. She’s there to take down a mafia operation tied to human trafficking. She’s there for the missing kids. For justice. For the ones who don’t have a voice.
But of course… feelings don’t care about missions.
She doesn’t fall for one of them. She falls for both. Because Dalton and Mac bring completely different pieces to her heart. And they love her just as fiercely.
So when the truth comes out — when they find out she’s undercover — the betrayal cuts deep. On all sides. The hurt. The anger. The feeling of being used. The fear that none of it was real.
The question isn’t just “can they forgive her?”
It’s: can love survive when trust is shattered?
And somehow… this story makes you feel every second of it.
Even this possessive, non-sharing romance reader over here was completely invested.

I am beginning to realise I love Biker romances.
The story was engaging, and the characters were likeable, which made reading it really easy. It pulls you in as Katie/Nicky falls deeper into biker life, questioning her future.
I love the why choose element and the found family theme. Pacing at points, I thought it was maybe a bit rushed, but other than that, I couldn't put the book down.
I always get knots in my stomach thinking about the final act when the secrets are uncovered and identities are revealed, and I loved the ending.
It has dark themes, but violence on the page isn't overpowering.
It's on the milder side of some of the other Biker romances I've read, but it was quite refreshing. One for beginners of the genre but definitely worth the read. I could have kept reading more from the Saints Club house!
There were a couple of chapters from Mavericks point of view, switching things up a bit, but it would have been nice to hear a bit from Dalton, too.
I will absolutely be reading Holly and Jackson's story 😍

A gritty story for Katie, Mac, and Dalton
This book was a surprise, in the best storytelling way. There is a note from the author in the front to mind triggers. This story follows a lieutenant Katie aka Nicky on an expected undercover assignment. Katie had not been trained nor had any experience but she was determined to bring to justice those who were stealing females in her town. Guess what? Katie finds out life is not always black and white, it is definitely filled with variations of gray. There are some serious moments, laughs, fights, spill the tea sessions, and big surprises. Read On!

What a solid MC + undercover cop why choose romance. Because, seriously…why fall for one brother when you can have both.
I enjoyed the romance taking time to develop over several months and the gradual development of the suspense plot. Revelations along the way were well done. The twist at the end was something I suspected earlier, then completely forgot about as the story progressed—and I loved being thrown for that loop.
The HEA epilogue was the icing on the cake for this.
This landed on my TBR thanks to the MC Romance Book Club and I can definitely see myself continuing the series.

I really enjoyed Riding the Line. Katie is such a strong character, and I loved watching her struggle between staying true to her mission and following her heart. The mix of danger, romance, and found family kept me hooked, and the two brothers added so much tension and emotion.
This is a fast-paced romantic suspense with characters who feel real and complicated, this is a great read.

Riding the Line had me hooked from the first page! The characters feel real, the story moves fast, and the mix of tension and emotion kept me turning pages. Definitely a ride worth taking!

holy cow i ate this book up. i LOVED these characters and the premise of the story it was so captivating. i cried, i had… other emotions. and my jaw was consistently on the floor. the spice was perfectly balanced with the plot in a way that honestly surprised me. Sarah is a phenomenal author and I can’t wait to continue supporting her as a person and artist. I’m itching for the next book as we speak.

Wow! I haven’t read a story like this in a long time. It grabs you from the very first page and just keeps getting better with every chapter. Katie is a strong, fearless heroine on a mission to take down a dangerous child trafficking ring. Her journey leads her to Dalton and Mac’s biker club, where she hopes to gather information—but what she finds is so much more.
As Katie digs deeper into the case, she also finds a sense of belonging and maybe even a family she never expected. But when she uncovers who’s really behind the trafficking, she’s faced with a painful choice: doing the right thing or hurting the people she’s grown to love.
Gripping, action-packed, and seriously steamy—this story has it all. Loved it!

Book 35 of the year. And truthfully this book was awful. There were so many plot holes and every other word was “I hope they can forgive me when this is all revealed in the end” it was just not my type of book at all.
August 6, 2025
I would actually give the book 3.75 stars. I did enjoy the book but never fully engaged with the characters. The plot was good but only the final third/quarter of the book seemed to be about the missing children. Don’t get me wrong, I want the romance/spice (which was great), but felt it overpowered the rest of the story. And the agent/handler ‘sub-story’ came out of left field, like the main character said, if he felt that way, why did he not help her when she needed it?!
I received an advance review copy for free, and I am leaving this review voluntarily.

This was amazing!! This had me in a chokehold the entire time. It was sooo well written.
August 1, 2025
WOW, what a long epic journey into deceit, danger, chaos, intrigue and love. Katie, Mac and Dalton’s story was amazing, I loved it ❤️❤️❤️ I was drained of emotions once I got to the end, my worry for Katie as I read this story, wondering if in the end she’d lose it all, would Mac, Dalton and Katie survive once the truth was out, my heart was double timing hoping they would as their love story was so beautiful. So excited for the next book. A definite page turner and very entertaining. 100% recommend this book to everyone ⭐️⭐️⭐️⭐️⭐️ you will not be disappointed 😎🖤
August 27, 2025
What an amazing book! Great story line, good suspense and action. Had me falling in love with every single character! Completely sucked me in from start to finish. Dalton and Mac are beyond swoon worthy 😍😍😍. I cannot wait for the rest of the series!

new author that I really liked. agent goes undercover into the MC to stop trafficking and discovers they are on the same side. ❤️‼️🔥

Worth the read! The job doesn’t stay the job… it becomes home. The people become family and family saves family!

I enjoyed this book! I was on the edge of my seat half the time.
I got sucked in after reading the first chapter. It started with an action scene with the main character.
I thought the scenes with Mac and Dalton were perfect. It was very spicy. Perfect mystery too. Shows the real struggles of what being undercover could be like.
I really wanted this to be a movie while reading the book!

I received a gifted e-ARC and this is my honest review.
✨Review Highlights✨
- Great start of a interconnected stand alone series
- Why choose romance
- Motorcycle club romance
- Good plot
- Fast pacing
- Interesting characters
- I would recommend, and I would most likely continue the series
I liked this book, it had a good story around the romance and a good plot outside of the romance. I would say that the romance and the story were pretty even in this book. I was really interested in the characters in this story, not just the MMC's and the FMC but all the characters in the story. It is really the characters and how they were written that makes me want to continue this series. I felt a connection to all of them and want to know more about the side characters from this book.
In regards to the romance in this book between the MMC's and the FMC I was a little bothered by it. I felt like within the why choose dynamic that the FMC liked one of the brothers more then the other. I have never felt that way while reading a why choose before and it made me feel at times that it was going to go from a why choose to a love triangle and that she was going to choose one of them. I really didn't like that. I love that it stayed a why choose however I really feel like the FMC liked one of them more then the other. It didn't feel like a balance of love to me, others may feel different but to me if felt like there was more feelings for one over the other. Do I feel like she loved them both? Absolutely, it just didn't seem like she loved them both the same.
I liked the writing, but I will say that if felt like a debut novel and I don't know if that is what this is, that is just what it felt like to me. There were some grammar mistakes which I really don't care about, but there were some inconsistencies in the story that where at times confusing until I realized that they were most likely mistakes. I still really enjoyed the story and felt like the author had great pacing throughout the story, which can be hard to do when your book covers a span of time well over a year.
I would recommend people read this if they enjoy MC romances with a lot of angst and suspense. I really enjoyed the story and I really connected to the characters. The writing isn't the best I have ever read, but I felt the story. I felt the characters emotions and was invested to find out what happened to all of them. I feel like if an author can capture your emotions, that is the best writing I can ask for.

This was my first book by this author, but it definitely won’t be my last. I was pulled in by the promise of a motorcycle club romance with reverse harem elements and it absolutely delivered.
Detective Katie McGrady is deep into a case involving missing girls when the FBI uncovers a potential lead. To get closer to the truth, she goes undercover as Nicole “Nicky” Moore, carefully crafting a persona that will get her noticed by the Steel Saints Motorcycle Club. It doesn’t take long before she catches the attention of Dalton and Maverick, two brothers who hold powerful positions within the club.
As Nicky becomes more embedded in their world, the lines between right and wrong begin to blur, and she’s forced to question everything she thought she knew. This story leans heavily into morally gray territory, showing that sometimes the in-between is where the truth really lives.
The author delivers a gritty, emotionally charged story that kept me fully engaged. I found myself laughing, gasping, clutching my pearls, and even tearing up at times. The spice is well done and adds depth to the relationships rather than feeling unnecessary. I also really enjoyed the side characters especially Nicky’s group of girls who bring humor, chaos, and a strong sense of found family.
The only reason this wasn’t a full five-star read for me was due to a few minor plot inconsistencies. They didn’t take away from the overall enjoyment in a major way, but I did notice them.
If you love morally gray characters, motorcycle club romances, “burn it all down” kind of love, and strong found family dynamics, this is one you’ll definitely want to pick up.

I went into this book knowing only one thing: it was about a motorcycle club and a MFM. Once I started, putting it down was impossible.
The plot and pacing are fantastic, and the story pulls you in from the very beginning. The characters are beautifully written, with so much depth and personality. The chemistry between them is incredible, and the slow build of tension and angst makes every moment feel earned.
The FMC is everything I love in a heroine—strong, sharp, and unapologetically sassy. And the MMC? Absolutely delicious. Their dynamic is intense, emotional, and seriously addictive.
The spice level was perfect for the story—though as a devoted why-choose girly, I definitely wouldn’t have complained about a few more group scenes together 👀🔥.
One of my favorite parts was the found family element. The side characters are just as lovable as the main couple. The girl gang and their men added so much heart, humor, and loyalty to the story, making the whole world feel real and lived in.

If you love a good MC romance, I definitely think you should check this one out! Sarah did a fantastic job with this, especially as her debut novel!
This book takes you on the journey of a detective who keeps hitting dead ends in a case of missing girls. In swoops the FBI, they believe they have a lead on who's taking these girls, and they want Katie to go undercover into a MC group that has ties to the DiAngelo mafia. Katie knew that this was going to be dangerous and she was going to have to be somebody completely different, but she wanted justice for the girls.
Katie, now turned Nicole, makes one heck of an entrance to get the attention of the MC and it definitely works. She meets Dalton and Maverick, the two brothers of the MC that are quite opposites of each other, but both draw her in immediately.
I love a good strong FMC, and this one delivered! There are emotions, suspense, spice, morally grey men, found family, and an FMC that is fighting the battle between her heart and her duty. The ending had a twist I wasn't expecting and then the epilogue tied it together so wonderful and almost had me crying (happy tears).

I love a good strong FMC, and this one delivered! There are emotions, suspense, spice, morally grey men, found family, and an FMC that is fighting the battle between her heart and her duty. The ending had a twist I wasn't expecting and then the epilogue tied it together so wonderful and almost had me crying (happy tears).

OMG!
First this story pulled me in from the beginning! This was my first romantic suspense and it did not disappoint. As we go through the story we follow our FMC who is a detective! But she goes undercover for a case she's been working on for a while. After months of training she meets our 2 MMC's who are hot! And absolutely perfect in their own ways! One of them is hot and brooding talk about one who is always grumpy! The other is fun and sarcastic in his humorous ways! Talk about the best of both worlds! Did I mentions they are brothers! And very very possessive over our FMC even with each other! 🥵🥵 of course with the romance came the suspense and the suspense was spencing! As I was reading I would think I would know what was going to happen but never actually did! My heart was racing so much throughout this story! And the ending omg! If you don't read the ending through the epilogue well then you're wrong! Because that ending was amazing and beautiful and I am crying because of how perfect it was!
I highly suggest this read! But definitely check your content warnings!

Great story
This was such a good read. Great character development.
Katie is a detective who along with her partner Shelly are trying to work a case of 5 missing little girls. When Katie's boss asks her to go undercover in a MC to see if wats going on there is connected to her case. She's never been undercover but this case meant the world to her so she agreed and became Nicky.
Mac and Dalton are brothers in the MC. Mac should've been Prez but after an ambush and injury someone else took the Prez spot and was taking the club in the wrong way.
They all meet when Nicky picks a biker bar and runs into them. A prospect didn't understand the word no and his bike caught on fire.
Katie/Nicky try to keep the lines and boundaries hard and not to cross them. But the more and more she was in and with everyone brother's included the lines blurred.
We watch their love story unfold and it's beautiful. Things happen and alot of emotions are flying....you have to read it to find out if the bother can forgive Katie or not....

Early in the book, I wondered what possessed me to pick up a MC novel. I'm just not usually a fan. This one was different, loads different. This was essentially a family who likes motorcycles, but likes saving people even more. The men respected their women, none of that "old lady" stuff except in jest.
The one thing that might have earned another star was better editing. The female protagonist is Katie, but the MC knows her as Nicky. But toward the end of the book, they call her Katie. A good editor would have caught that. Throughout the book, there are missing words and words that don't sync with the rest of the sentence. It might not matter to a lot of readers, but this former English teacher noticed and it threw my out of some crucial places in the story.
Otherwise, engaging characters, no glaring loose ends, a decent read. This author has potential.
I received an advance review copy for free, and I am leaving this review voluntarily.

Five young girls have disappeared without a trace. Officer Katie McGrady and her partner are at a dead end until she is offered a chance to go undercover as Nicole Moore with a biker gang. She takes it.
Except the gang isn't what the FBI tole her it was. Except the two brothers in charge break through her careful wall to keep this assignment only an assignment. Then most of the rest of the gang do the same.
Each step taking Nicky/Katie closer to solving the case takes her closer to the gang and to the deadly gang behind everything.
The book is a fast read. The story line is good. It does get a bit contrived in places and is predictable in others, but still makes fun reading.
One flaw is the graphic sex scenes. They are worked into the narrative well, but are really not needed in such detail. These read like juvenile fantasy sex encounters and break up the story.

I picked this up at a local bookstore where Sarah was signing Riding the Line. This book has elements I am interested in, and she's local, so why not give it a go? Make sure you read description/trigger warnings as it may include topics that are upsetting. (It is a why choose with a pair of brothers but no ⚔️.)
I loved it. Reading Katie/Nicky, Mac, and Dalton's story was a fun little ride. It had just enough suspense and romance as she infiltrates a motorcycle club to take down a trafficking ring. She quickly discovers things aren't what they seem and finds she enjoys the club and the friendships it provides. The epilogue is chef's kiss.
I cannot wait to get to read Jackson and Holly's story!

I just read Riding the Line, although this was not a typical read for me. The story summary captured my attention, so I decided to give it a try.
Detective Katie McGrady is asked to go undercover as Nicky Moore to infiltrate the Steel Saints Motorcycle Club with ties to the DiAngelos, a Mafia family. This is to hopefully solve a trafficking case she and her partner, Detective Shelly Vaughn have been working on. Katie is young, smart, and eager to learn, so she accepts.
Nicky infiltrates the Steel Saints MC and begins working at their clubhouse as a cook and cleaning person. Mac and Dalton Mills are brothers in the club, and the President is Silas Greyson who is not only scary but also a sleazeball. Nicky is attracted to both brothers and has a relationship with both.
I enjoyed the story, but there was too much sexual detail for my liking, particularly when it was with both Mac and Dalton. What I did like was how the club was like a family, and how Nicky became such good friends with two of the wives, Maria and Holly.
Will Nicky (aka Detective McGrady) take down the Steel Saints MC and the DiAngelos? If so, what happens to her relationships with all these people? Will she just walk away and return to the police force? You need to read this suspenseful story to find out what happens!
I received a copy of this book via BookSirens and my honest review is my own voluntary opinion.

Katie is a decorated cop that has been assigned to go undercover tonight filtration a mc club that could be involved with trafficking.
Now Nicky she immediately catches the eye of 2 brothers who run the club Dalton and Mac. She starts falling in love with the club and the men and their family. She uncovers that they are not sho thr fbi think they are.
This book should have been a novella I think it would have flowed better. Some parts were a tad too rushed and I felt like we really didnt get much Dalton after the cabin. The authors note made me think it was not going to be a hea but dont fret. Love Holly and Maria alot. I think this was rushed and slow in some parts made this not flow correctly.
