****"It's like getting half the series for free!!"****
Book 1
Never Letting Go :
Ten years ago I messed up. I pushed the one thing I loved the most away. I watched her run as far as she could. I ruined the love we had. I threw myself into the Marine's thinking I could get her out of my system. That didn't work.
When I came back I got the worst news ever. Or so I thought. Now I'm forced to keep a promise I made and find the one girl that stole my heart.


Book 2
Learning To I fought my way through life. Family was an important part of that. I kept myself away from them not wanting to see the disgust of my father. My club was all the family I needed. When I was taken and forced into a living hell, the one thing that kept me going was the unknown girl next to me. Getting her out alive was my priority. After I do, I have to make the toughest decision of my life.

I was never wanted. My father used me to his advantage. I was taken for his debts. I thought I would die. I wanted to. That faceless man that kept me going was all I looked forward to. Until he was gone. When he finds me again, I have to learn to love. Can he be the one to show me how?

Book 3
Fighting For A I was a fighter. I was good at it. When I met Laura I thought I was having a round of hot sex like usual. When I saw her for who she truly was, I wanted more. A lot more. She had her own problems but I wasn't ready to let go just yet. I'll fight for what I want even if she does push me away.

I have a past that won't go away. Literally. Hector hasn't gotten the message that I don't want him. A night with Dax turns into more. I didn't plan on it. Every single time I turned around, he was there and I found myself liking it. But Hector remains a problem. A problem that quickly gets out of hand.

Book 4
Keeping Unhappily married. Yeah, that sums up my life. I messed up with that decision. I still have my sister though. When I attend her wedding, I run into an old friend. Ivy. When she admits that she had feelings for me, I take her home like any good man would do. I didn't expect all the complications that came with it though. She was used before me and I want to show her that I'm not the same as him. The problem is, I am.

I fought cancer and won. I fought a useless husband and won. When I see Kane again, I lose. Badly. I always had a crush on him when we were kids. I never thought the feelings would still be there years later. One night with him and my world is thrown off balance. His club is his life and I know that. When my cancer comes back in full force, I do the one thing I can. I run. He will chase me. He told me he would. When the tables turn, will I do the same?

Book 5
One More Sebastian
Blood. Death. Darkness. Those are things I know. Drinking. Walking away. I was good at that. I messed up one night when I slept with the President’s niece. We were both drunk and out of control. Now she’s pregnant with my kid. I can’t be a father. I don’t want to be. At least not at first. After a hit goes wrong, I change my mind.


Book 6
Promise Of I was a virgin. Jordan was the girl that changed my outlook on life but truths and lies threaten to rip us apart.

I am a wife, mother, child chauffeur and author. I love being able to create different characters and spin a web that makes them come together in the end. My books do not stick to just one genre, they span many.

I write about things that are real life situations and fairy tales are not always smooth sailing. My MC books are hard and gritty and they have struggles just like you would in life.

I also have books that are not so in your face. There are several that are good love stories that are fraught with issues that the characters have to deal with.

I loved all 6 of these books. They weren’t all unicorns and foo foo shit! This is how I imagine a MC to be. They are family. They protect what belongs to them. They are ruthless and killers when the need arises. The characters are flawed but it works for this group of alpha men and their women! I think if I had to choose, I would say Bash’s story was my favorite. I even shed a tear or two.... how could I not? Loved this series.

One wild ride

This box set is packed full of action, underground fights, brotherhood, & love. Easy book gives you an in-depth look into one of the hot AF alpha men of the Knights of Sin MC & the woman who wraps them around their fingers. Could contain triggers for some & full of adult content/situations. I hope to see more from this MC!

Never Letting Go
Oh man why do I fall in lust with each of these MC guys!! This author is so good about giving us story and passion and mixing it up so we don't get bored with either one. This story is so touching watching these two broken souls mend each other and that's what they do when things get rough. They never thought they would see each other again but when tragedy hits that changes. This author does a masterful job of drawing us in and making the pain our pain as we become invested in the characters and their success. Wonderful read.

Learning to Love
A father's love is a special kind of thing. Well at least it is for most people but Bullet and Trinity may not agree with you. Their fathers are how they got into this mess in the first place. But that mess is what brought them together. In true form this author brings us a story that covers the full gambit, torture, rape, murder but most importantly healing and love. MC's love hard because of who they are. Discarded by the public for their appearance, belittled by outsiders, withdrawn from the "normal" world. They are a nation within a nation a family bond like no other until it is broken. Bullet has been broken by his time in the military and an old love but when he meets Mouse (Trinity) he finds home, he just has no idea how to get them from where they are to where he wants them to be.

A beautiful touching story that will rip out your heart before it's pieced back together with bows on it. Love this author and love her style. This is the bomb.

Fighting for a Chance
Dax is the one who is the enforcer but also the one that is cool under fire. That is until he meets the girl with the beautiful blue eyes that steal all of his marbles. She has no clue how he gets her but he does, but when he puts her unknowingly in danger they both may be in for more than they planned. The MC family is back in the forefront and it I time for another one of the unfiltered loud and proud brothers to go down hard.

I love this author and the MC family she has introduced me too. I find myself losing all composure when it comes to their lives, their loves, their losses and their victories. These boys love hard and play harder and Dax is no exception. Great story to add to the collection.

Keeping Faith
A woman who has cheated death. A man who has no fear of death. The combination is explosive especially when they have a past. With friends and family who know and love them both they have no way out. The pain and emotion that feels this read is pure Erin Trejo. This author pours so much emotion into each read. The pain of being kicked when you're down by the one who is supposed to love and support you hits them both hard just like their love. Great read and characters that just tear you up and put you back together. Love this crew.

One More Try
I had to take a day or two away to write this review especially after this emotionally packed story of Shannon and Bash. I have to say Shannon had me reeling and earning mad props for so many reasons as beaten, battered, abused, gutted, tossed to the side, as she was this girl held it together. Oh she just about broke my heart. That is what was left after Bash. . . oh yeah I got suckered in by this author again and I really think I must have some emotionally masochistic tendencies because I continue to read this MC series. Why in the world do I keep reading this author's books that have me bawling one minute and ready to act out the next?

Bash and Shannon both have such a gut-wrenching past individually but hell so do the rest of this MC. They are all unique and finely chipped china. They aren't broken but that's because they have other's who get them and help them heal. They fit. An amazingly emotional healing read, that leaves you wanting yet afraid to know what this author will do next.

Promise of Love
Link’s story is just what I expected. Link has choices taken from him and he is forced to do something that tears him up emotionally. But now he has a new bird to watch over and keep safe. She has so many secrets. Secrets that may destroy her and anyone close to her, but Link wont let go. Breaking down her walls will be difficult especially since he isn’t really sure what they are.
My heart broke for Link because he is the sweetie that takes care of everyone and yeah if you read the last book you can see where it has gotten him. Plans will be made, lives will be traded, debts will be paid, love will flourish, but first, an abuser has to be found and dealt with and so does that doggone club that keeps popping up. Great story, love this club and this author.

Good series

I really liked how all of the books flow together. You met the characters of the next book in the previous book so they were familiar to you. I loved how flawed everyone was. My only negative reaction was to the ending of the series. I just thought it was weak. So I would’ve given us a 4.5.🔥🔥🔥🔥🔥/5

Loving this series as a whole. There are a few issues such as repeatedly using wording and phrases, such as ROARS and SCREAMS as descriptive words. Erin brings you into the MC world as a novice, you leave with intimate knowledge and a wish for more.

Erin Trejo has a way to tell a story that will captivate you. In this box set you’ll get 6 amazing books.
Never Letting Go Book 1
Micah and Aubrey have love, tragedy, and hope of a second chance. While both characters are broken they both are strong in their own way. Aubrey is a firecracker full of sass while Micah is an alpha-dominating man to be reckoned with.
Learning to Love Book 2
This book is filled with grit, anguish, violence and drama. Bullet and Trinity will pull at your heart strings and won’t let go.
Fighting for a Chance Book 3
This book is about Laura and Dax. The chemistry between this is hot and off the charts.
Keeping Faith Book 4
Kane and Ivy’s story is no different than the previous books with the plots, twist and turns however this one has sadness and perseverance.
One More Try Book 5
This book is about Sabastain and Shannon and let me tell ya if you love dark and deep characters you will LOVE this book. Shannon is trying to overcoming tragedy while Bash is pure evil. This is my favorite book in this series.
Promise of Love Book 6
OH Erin, Erin, Erin…… What a bitter sweet ending. Promise of Love is Book 6 and final in the Knights of Sin MC. This is Link and Jordyn book. Link is the techy guy of the club that wears his heart on his sleeve however in this book you also see the pure alpha male.. yummy. Poor Jordyn. Her story is heartbreaking. When those two come together in a forced situation it started a bond. This was a great ending for a great series!!!
I highly recommend this series… a must read.

You will fall in love with each and every hero and heroine...I can't even begin to decide on who's my favorite, on whose story is the best! I think I know but then I start the next one and my choice flies right out the window!

Erin Trejo always manages to get your attention with her alpha MC men, and their resilient ladies!!! This boxset of Knights of Sin MC was really good reading, and couldn't even tell you which one in the series was actually my favorite. There were a couple of the stories that I wanted to reach out and smack the women. MC life must be among the toughest there is, but any woman that goes into that life should know that before hand not after you get there. Getting drunk enough to take half of your clothes off and shaking things for the members on a tabletop at a party is not the innocent little miss game to play with those kind of men, or any men really! Other than that I enjoyed the stories very much!

A final editing pass would have been good. Some serious wrong words, words missing, etc. could have been eliminated! I am a horror about that. No matter what I pay for a book I am expecting the author to give me a perfect read! That simple!

Never letting Go
3.5 stars

Parts of this story was really good and other parts just felt like a copy of so many other MC stories. That being said, this still kept me reading because this author definitely has skills when it comes to writing. I will be looking for more from this author.

I read this as part of the Knights of Sin MC boxset.

Learning to Love
3.5 stars

Learning to Love was the second book of this series and had many good elements. However, I struggled with certain details. The transitions were rough at times between scenes such as someone being shot and being knocked off a porch but then there wasn't a real explanation of what happened next. However, this author does have an ability to draw the reader in that compels them to keep reading, so there is that. I read this as part of the boxset.

Love the men and women of the Knights of Sin MC

Each and every story in this box set is a standalone, but as a series of is amazing. I loved meeting each and every character and learning what made them who they are. They are all strong individuals with a burning desire for justice no matter what the cause. They will go down fighting for their club which is their family. You wrong one you deal with them all. Highly recommend this series.

I think I was like most of Erin Trejo's readers when i read the first book and instantly needed to know every member of the Knights of sin and they are all here in this six book boxset .
Their stories are intense , emotional , packed full of Bloody action ,romance and sultry keep your drool bucket ready Sex scenes that will keep you satisfied .
I love how everyone in the MC stood together , even in serious situation that the author tackled very well .She made them stand tall and together unbreakable.
The Knights of sin series has been one of my favorite's and it's sad to see it come to an end , but I cannot wait to see what Erin has up her sleeve next.

Loved this series!! Give me more...hated that it ended, wished we could have heard about more of the men and women of the Knights of Sin...
A bunch of men that didn't seem to fit in anywhere.. men who needed to have blood on their hands but they didn't kill just to be killing, no they killed others who harmed others and used others... They didn't think they needed anyone else except their brothers but they found their half of their souls and they defended them but most of all they loved.
This is a great complete set so if you're into MC romance look no further.
Definitely for adults and don't cross between any of the writers other series.

Another wonderful series by Erin Trejo! Knights of Sin MC had everything a MC series should be, it was filled with emotion, danger, violence, abductions, murder, and loads of passion. This family of sexy alpha brothers and the women that come into their lives will captivate you from the first book as these men will do anything for their club as well as protect the women they love. By far my favorite was Promise of Love: Link. Each story will have you on edge from beginning to end. This is a must read series and one that should not be missed. I highly recommend this series to all Erin Trejo's fans!

Hang on to the edge of your seat with these alpha men

I would recommend this book to anyone. I was never really into it at least thought I was never into stories about MC clubs, however as soon as I read the first story in this collection, I couldn't wait to read the next one and so on.

Each alpha male and the women who have their love, devotion, and heart are absolutely the best. Something different about each one of them that make this a collection a must have.

Will be on the lookout for more MC books by Erin. She writes the story that makes you feel as though you are part of the story. She puts the right degree of emotions into each story!

I read all six books of the Knights of Sin MC box set, I am seriously impressed with the entire story line the plot twists and turns and how each book follows into the next.

As you read and get to know each individual character in the the MC you’ll find yourself getting invested into the entire story line and unable to put them down until you get to the end!! Only to find out there will be a novella and someone’s getting married, I am not telling who I think it is. Get each book on its own or buy the box set but y’all need to read these books!!!

Complete six book MC series. Each book about a different brother in the Knights of Sin MC. Each story told in dual POV with HEA. Secondary characters and storyline the same throughout the series. Just the right amount of steamy with plot and club business. There is club violence with kidnappings, beatings, and all that goes with it. I enjoyed the brothers and their old ladies. The women were strong when needed and soft when their men needed that too, but no pushovers! I would have loved an epilogue to see what all the brothers and their families look like in the future!

Knights of Sin MC. (Box set 6 book series)

Great storyline. Each book takes you on a ride & let you each of the Brothers in a way you won't believe. I loved each story. I think Link was my favorite brother.. But My favorite story was the one where Cancer hit close to the family. Don't want to ruin it for anti e who hasn't read the series yet.. Can't wait to read the next book in this.. The Novela...

Fantastic series!
Loved everyone of these!
So easy to connect with each character and their women.
Each one packed with a handful of different emotions that you cant help but feel with them!
Erin is class! And just makes it so easy to fall into her books and get lost!
