My Stepbrother Biker

Summit Hill Vipers #1

by Nikki Landis

From USA Today Bestselling Author Nikki Landis comes a steamy, forbidden, morally gray, bad boy/good girl, MC romance—the first in a new series with an adult fairytale twist.

Letty:
One reckless, wild, uninhibited night changed my life. I dropped the good girl mask, and for the first time, I felt free. Gage Blade showed me exactly how tender and intoxicating his touch could be. He carved a place into my heart, and I fell hard for the bad boy biker.
Until he rejected me.
A few months later, our parents got married. My one-night stand and personal tormentor became my new stepbrother with two more at his side. I'll never consider him family. I won't forgive or trust Gage ever again.
My stepbrother biker has now become my enemy.

Gage:
Letty became my obsession the night she let me touch her, doing wicked things a good girl like her should never consider with a guy like me. My life is too dark for her light.
But when my enemies discover my weakness, and Letty becomes a target, I know I have to protect her.
Even if it's against her will.
She says she doesn't need me, but I know better.
I'll lie, cheat, steal, and kill to keep her safe and claim her.
Even if I have to burn down the world to make it happen.

Gage and Letty

What a great start to The Summit Hills Vipers MC which is a new series. This is a quick MC romance with Letty giving up living the perfect good girl life, for just for one night. Little did she know that Gage would end up being her stepbrother.

If you love your books packed full of secrets, steam and plenty of action this is the book for you. This author never lets me down with her awesome MC books. I’m just glad that I have another series by her to follow.

Didn't like it at all. I think I'm over reading about teenage girls getting off with 18 year old sex gods. We all know they don't know where the clit is. Anyways, the only good thing about this was the H being celibate after having eyes only for the h. But again the whole teenage lust and hormones I'm done with. The plot was also choppy because it's only 158 pages and moves around constantly. Then towards the end it jumps four years. The writing was just too immature for me. Well considering it was about teenagers. I thought this would be years down the line when both were adults. My mistake.

Exciting!

Story: ⭐⭐⭐⭐⭐
Trope: step-brother
Angst: 😱😱
Smexy: 🔥🔥

If you're looking for a low angst, quick read with an off limits step-brother trope, then this will definitely tick your boxes. Fast paced with lots of action , this is a perfect palette cleanser in between heavier reads. Exactly what I was looking for!

[Charlotte Isaac]

Wow. What a story. I couldn't put the book down once I started.

I loved Gage and Letty together, they had a lot to overcome from their childhood. But they manage to work through it all with highs and lows.

I highly recommend this book.

[Barbara]

OH My Goodness, what a wild ride My Stepbrother Biker took us readers on. Ms. Landis has given us a well written book with the absolute perfect characters. Letty and Gage met in high school. Letty was a shy good girl from a good family while Gage was the school bad boy whose family all but ran the town. One senior party changed both their lives. It’s the night they truly met and spent the night til sun up together. But the magic ended the next day with Gage rejecting her, embarrassing her in front of the whole school. To make matters worse, their parents got together and married a few months after their magical night. At the reception, Gage danced with Letty and whispered she was his and he’b be back for her in two years. From here the book takes off on a ride of lies, betrayal, revenge, romance and so much more. The twist and turns kept me on the edge of my seat while wishing for any type of happy ending for Gage and Letty. But was that even possible? Was Gage the monster everyone thought him to be?

Excellent read that this reader highly recommends. I can’t wait to see what happens next with the Summit Hill Vipers MC.

2 Thumbs Up and 5+ Stars

This was sooooooo good. Gage and Letty meet in high school and spend one night together. Then something happens and Gage ignores Letty. She's hurt and doesn't know why Gage is treating her this way. Then their parents get married. Well that throws a curve ball in their lives. Or does it? I will say this one was very enjoyable. It shows the beginning of their relationship or maybe I should say journey,because that's what it is. Damn the crap they go through. But will they come out together? Nikki Landis sure can pull you in with every book she writes. If you're debating what to read pick up any one of her books and you'll be hooked and have a new favorite author.

[Amanda M]

I always love when I find a book by this author because they just have a way of writing their stories that draw you in. And this book did not disappoint. I loved that it was a forbidden, morally gray, bad boy/good girl MC romance with a twist. There is a lot that goes down in this but not so much so that it takes away from the overall storyline. In fact it's just enough details to deliver an incredible narrative. It’s a quick read but so good and worth the read. I can't wait to see what's next in the series.

[Mimirureviewbooks]

Another must read from Nikki Landis!!

I absolutely loved this book! Like… read-it-in-one-sitting, ignore-my-responsibilities, emotionally-invested level devoured. It’s another awesome book from a very talented author. Nikki Landis did an excellent job with Gage and Letty story, full of great characters, family drama, lots of action, danger, twist and turns, secrets and so much more.

[Shannon Godwin]

I loved this book! I’m not usually into the step siblings books but this one is not the usual story and I absolutely loved it. Gage will do what it takes to protect Letty. I love how there’s no cheating in this book and although they aren’t together there’s no talk of him not being loyal to her.
This book kept me so wrapped up that I didn’t want to put it down. These two go through so much, they deserve a HEA.

[Rhonda Cave]

Awesome!!!

Wow!! Letty and Gage (Blaze) meet in high school. Little does Letty know that the guy she is lusting over in school will soon become her stepbrother. When Gage graduates and joins the Vipers, Letty never sees Gage but he makes it his duty to watch over her. When she graduates they think they will get their happily ever after but are they in for a rude awakening. His father is no good and Gage soon finds out how bad he is.

[Cindy L]

Great start to a new series!

Love the newest by Nikki Landis! Gage & Letty are perfect together. Their chemistry is off the charts & I love that we were able to follow their story from high school on. I clapped, I laughed & once even cried, while reading this. Highly recommended, and a definite addition to my library!

[Lora Cimino]

Love love loved it!!

I had been waiting for this book to come out. You can expect a great story from Nikki Landis. This is Blaze and Letty's adventure that leads them to danger and threats. I had all the feels with this book. I started it earlier today and didn't put it down, I just read it in one sitting. This book is spicy and romantic. I hope this is just the beginning to a series.

[Renae]

10/10

[Angels]

What a wild ride featuring Gage and Letty that consumed us with mystery and suspense. Their lives changed after a senior party where they spent a beautiful night together until sunrise.

The story unfolds with lies, betrayal, revenge, and romance, keeping readers on the edge of their seats. The twists and turns in the plot kept me engaged, hoping for a happy ending for Gage and Letty. Although your heart breaks for them, it becomes clear that sacrifices had to be made to ensure a future for them

Their chemistry between the two is pure fire. Even when Letty claimed to hate Gage, her heart longs for the man. Gage, on the other hand, knows from that night in her arms that they were destined to be soulmates.

The plot twist was the best part. We did not see that coming and were pleasantly surprised. This book is an excellent read that I am eagerly looking forward to the next installment in the Summit Hill Vipers MC series.

[TWR]

one castrophe too many

I ultimately settled on 2 stars, though I came very close to giving it 1. What makes this especially frustrating is that the story had the potential to be a solid 3 or even 4 star read.

Instead, the author fell into the common fast fiction trap of piling catastrophe upon catastrophe onto the main characters. Not every chapter needs another crisis. After a while, the constant stream of drama becomes repetitive, exhausting, and far less believable. Fiction still needs an internal sense of realism, and this story lost that.

I genuinely think this book could have been much stronger with a substantial rewrite that focused on developing fewer, more meaningful conflicts instead of relying on relentless misfortune to drive the plot.

The reason I didn’t rate it lower is because one aspect rang true: I believed the male lead genuinely loved the female lead. That emotional connection kept the story from falling to a 1 star read for me.

[Tina Locklear]

This happens to be Gage & Letty's story he is a part of the Summit Hill Vipers and he is the Stepbrother to the girl he is in love with only by marriage so this is not full blood relation but still forbidden fruit because she is stepsister and sixteen at the time his Prez forbid any relationship till she was eighteen, Letty was left to be harassed by Gage's half-brothers because he left to join the MC, he already knew he couldn't keep his hands off her. This one is full of twists and turns and lots of action and crazy emotions such as revenge, lust, hate and lots more, page turner from the beginning.

[Christine Woinich]

4 1/2 stars. Letty was hurt by Gage/Blaze and his two half-brothers when she was young. Gage didn't explain his leaving except he did tell her he was coming back for her. It took a couple years for things to really come out, and these two were able to find their way back to each other. I loved the fact that both Letty and Blaze had stayed loyal to each other, no other romantic partners. Deep inside they knew that they were meant to be together. Danger, revenge, and more surrounded everything that happened. A good story, and I look forward to the next in this series.

I received a copy through Enticing Journey Book Promotions, and this is my unsolicited review.

[Renee]

I received a copy of this book from the publisher/author to review for Stephanie's Book Reports.

This is the story of Gage and Letty. These two met when they were in high school and have spent one night together. However, he pretty much ignored her after that. What they never expected to happen was for their parents to get married. Letty of course was hurt and confused after Gage began to ignore her. But now they are a family, and you have to read to find out what happens. This is a quick read that is really good. I love a good journey through a mess of your own making. There is a lot going on in this book and it will keep you on your toes. This is a book that you do not want to miss.

[Cheryl]

My Stepbrother Biker by Nikki Landis is the story of Gage and Letty. They are step-siblings after his father and her mother were wed. They like each other a lot and then…he just leaves. He does make a promise, but he’s gone. Then, events start happening with her stepfather that put her in serious danger. Things start to spiral after that and her situation becomes more and more dire.

Whew!!! What a wild ride!!! So much happening and so much just keeps happening!! Exhilarating, exciting, nail-biting, danger-filled story that I could not stop reading. Very fast read and ever page is packed with tension, shocks, and unexpected situations!! Fantastic read!!

[Cheri]

My Stepbrother Biker: Summit Hill Vipers Kindle Edition by Nikki Landis due 3/2 (OR 10)/26
Gage & Lettie

Age doesn't matter--unless--she's under ager. He'd barely touched her before he had to ghost her. Years! He had o wait years. Could he? Would she understand when he could be with her? More complications with her mother and his father marrying. Worse yet, she needs protection. That is not something that can wait.

When they can't talk it over is it possible to overcome and come back together --ever --?

I enjoy reading the authors work. I am sure you will as well.

[Paige Wuerdemann]

Thank you Nikki Landis for the ARC of My Stepbrother Biker!

This is book one in the Summit Hill Vipers MC and starts off with a bang! The book was face paced and a page turner for sure! Letty gives up her perfect girl image for one night with Gage before it all comes crashing down. Gage turns out to be her new stepbrother and things aren't always as they seem.

You'll have to pick up the book to find out more about their story!

Excited to see what comes next in this series!

[Ann L]

Letty’s one wild night with Gage turns into heartbreak when he ignores her and his brothers start rumours, to make matters worse, he becomes her stepbrother when his father marries her mother.

Shes’s dubious by his about change when at the wedding he gives her promises but Gage is forced to stay away by his Prez because of her age… finally he can claim her and when she’s in danger, he won’t hold back.

This is dark, intense, and full of drama.

[Fran Zoch, LSoR]

when a good girl goes a little wild , a one night is ok until their parents get married and he becomes your stepbrother/ tormentor, the old saying goes fool me once shame on you fool me twice shame on me well there is not going to be a third time , well you have to read this book to find out if it happens or not

[Debbie Earley]

Gage and Leti have been through so much yet no matter what is thrown at them they still come back to one another. Secrets, drama, danger, action, steam, loyalty, brotherhood and justice being served fill these pages and I devoured this book in one sitting. Congratulations Nikki on a an amazing start to a new series.

[Sassy Southern Book Blog]

It is no secret I absolutely love this author. The way she pulls you into the story without it being so long that you lose interest. This story has the hero that is rough around the edges and a forbidden love. Gage and Letty make you fall for both of them!! Absolutely recommend!- Tasha

[Jen]

Usually like NL books but this one was a miss. The writing was all over the place. The characters were basically teens still in high school for a majority of this short book. One of my least favorite tropes is teen drama. Disappointing

[Lynne Garlick]

Wow! What a read!! Gage and Letty appear to have a love/hate relationship but she wasn’t seen what has been going on behind the scenes and her mum and his dad got married!!
Holy shit!! Holy whiplash!! And all the freaking feels!!!

[Michelle Graves]

It was really good it was interesting how they met and got 2gether. He has 2 find a way 2 bring down his dad. When evil spreads there's only 1 way 2 get out of it.

[Marie]

love this story

Gage is stepbrother to Letty. His father and her mother get married, that’s when the he*l starts. There are lots of twists and turns. I highly recommend this.
