Diesel’s Vow: A Tempest Knight’s MC Age Gap, Single Mom, Friends-to-Lovers Insta-Love Romance
She’s the family he never thought he deserved. He’s the home she never thought she’d find. But when her past comes for her, can he protect her without losing everything?
Diesel
I’ve loved Sienna Carter since the moment she walked into my best friend’s bar looking for a job. She’s everything I’ve always wanted in a woman—brave, beautiful, and a damn good mom to her son, Colt, who feels like the kid I never thought I’d have. But Sienna is also 15 years younger, and I’m an outlaw biker with a past soaked in blood and prison time.
So I’ve kept my distance. Vowed to protect her from afar. Made sure she and Colt were safe without crossing the line I set for myself. Until she started tearing down the walls I built around us.
Then, when her past catches up and threatens to take her and Colt away, I realize I can't stand to lose the family I never thought I deserved.
Now I’ll stop at nothing to save what’s mine.
Sienna
If there’s ever been a cautionary tale about falling from grace, I’m it. Raised in an ultra-religious family, I was supposed to be the perfect daughter. But one frat party during my sophomore year at Oklahoma State changed everything. I woke up sore and foggy… and two months later, found out I was pregnant. I couldn’t even remember losing my virginity.
When I told my parents, they didn’t care about the circumstances. To them, I was a disgrace. They kicked me out, and I spent years working dead-end jobs, trying to give my son, Colt, a stable life.
Now, we’ve finally found a home in Broken Bend, South Dakota—and with it, something I never a family. The Tempest Knights MC took me in, but no one’s looked out for me like the club VP, Diesel. He’s been there from the beginning, watching over us, loving Colt like his own. And I know he feels something for me, even if he refuses to admit it.
But I’m done waiting.
I’ve finally found a place where I belong, and I won’t let fear—or my past—steal it away. Can I convince the broken biker I love that he deserves happiness, too? Or will the demons from my past tear it all apart before we even have a chance?
The Tempest Knights MC is packed with morally gray heroes who’ll do whatever it takes to protect the women they love. If you crave fast-paced, insta-love romance with a touch of suspense and a HEA—jump on, hang tight, and enjoy the ride .

From the first page of Diesel’s Vow, you know you’re in for a ride—fast, emotional, and impossible to put down. Eliza Rockwood delivers a story that’s equal parts heart-stopping romance, family devotion, and just enough danger to keep your pulse racing.
Sienna Carter is a woman who’s endured more than her fair share of heartbreak, raising her son Colt alone after a past that left her abandoned and judged. She’s strong, brave, and fiercely protective of her little family—but she didn’t expect someone like Diesel, the club VP of the Tempest Knights MC, to see her as more than her past. Diesel is a broken biker with a dark history, but he’s loyal, honorable, and instantly smitten with Sienna and Colt. Watching him struggle with his love for them while keeping them safe adds a tension and sweetness that hits like a punch to the heart.
The romance is instant, yes—but it’s also real, grounded, and deeply emotional. The connection between Sienna and Diesel feels immediate and believable, yet Rockwood doesn’t shy away from the obstacles they face. Sienna’s fear of losing the home she’s finally built, the threats from her past, and Diesel’s own emotional walls all make their eventual love feel earned and satisfying. For a story that’s just 160 pages, Diesel’s Vow packs a serious emotional punch. There are moments that will make you tear up, moments that will make you smile, and moments that make your heart race with worry and hope.
This book is a perfect blend of MC excitement, spicy romance, and emotional depth. The characters are strong and lovable—Sienna is a vibrant heroine who knows her worth, Diesel is the honorable, loyal hero you’ll wish existed in real life, and Colt adds just the right amount of sweetness and charm to the story. It’s short, yes, but every page counts, keeping you hooked from the first glance across the bar to the final vow that ties their family together.
Diesel’s Vow is more than just a romance—it’s a story about loyalty, trust, and finding a home in the people who love you. If you’re looking for a quick, deeply satisfying read that will leave you smiling, maybe a little misty-eyed, and absolutely believing in love that protects, cherishes, and never lets go, this one belongs on your bookshelf.

Review of advance copy received from Author
Everything you could want and expect from one of Eliza Rockwood’s insta-love novellas: spicy, fast-paced, action-packed, and packed with real substance.
Sienna is a single mom who has been outcast by her deeply religious family after one reckless night changed everything. Struggling to make ends meet and give her son, Colt, the best life possible, she’s been bouncing from job to job just trying to survive, until she meets Diesel.
Diesel is the VP of the Tempest Knights MC and has sworn off relationships because of his past and the danger that comes with his life. He doesn’t believe he can truly be the man Sienna and Colt deserve, but that doesn’t stop him from being instantly drawn to them. Protective, possessive, and fiercely devoted, Diesel will do anything to keep them safe. He believes Sienna understands the boundaries he’s set, that he can never truly claim her, until one fateful night when she makes it clear: it’s all or nothing.
After months of silence and avoidance, Sienna’s past comes back to haunt her, and the only person she can turn to is Diesel. Can they finally face their fears, heal old wounds, and choose each other?
I loved Diesel’s devotion and the way he stepped up for both Sienna and her son. The chemistry was instant, the tension was delicious, and the emotional payoff hit just right.
I cannot wait for the next book in the series!

Review of advance copy received from Goodreads Giveaways
She grew up in a very religious household, and after she went away to college and came home pregnant, they disowned her. She has been moving around with her son, trying to find a foothold in a life that they can flourish in and she meets him. From the minute, she meets him there’s an instant attraction, which surprises her because he’s 15 years older and a biker with the local MC. But he is also the hottest, kindest and best person she has ever known. Unfortunately, he keeps her at a distance and it’s driving her crazy. He has loved her since the second he saw her and her adorable son, but he knows he’s done things in his life that he’s not proud of and he doesn’t want to taint her with his past. He will do everything for them, but love her up close, until he realizes that she is ready to move on if he doesn’t step up. He is a hot handsome biker with a heart of gold, a strong protector of both her and her son. She is a fierce little mama bear and willing to push him out out of his comfort zone if he won’t step up to the plate. When they finally get on the same page, they are magic together. It is hot. It is steamy, it will melt your panties right off, and it brings a happily ever after.

Eliza Rockwood delivers tension, danger, a found family that everyone wants to be part of, and a romance that will have everyone wishing it was there in just a few pages! I think this was my favorite book of this series so far, I was hooked!
Sienna has been through so much in her life, but let me tell you she is strong, brave, and she is fierce. She is a single mom and she will do whatever it takes to protect her son. What she didn’t expect, Diesel, the VP of Tempest Knights MC. Diesel is broken, but he is loyal, honest, fierce, protective and obsessive. And when it comes to Sienna and Colt, he will stop at nothing to make sure they are safe.
Watching him struggle with his feelings for Sienna and his dark past making him believe he isn’t good enough for them, broke my heart. This man is everything they need. The story may be short, but it’s packed with lots of tension, an amazing family dynamic, and delicious spice.

Eliza did it again. I absolutely love the Tempest Knights MC series, and Diesel’s Vow was no exception. Every book in this series has been such a joy to read, but this one truly stole my heart.
This story follows Sienna and Diesel, and it’s everything I wanted from a short MC romance. It’s sweet, emotional, with a little bit of danger and full of that delicious insta love. The connection between them is intense and beautiful, and it pulled me in from the very first pages.
I’m not someone who usually cries while reading, but this book caught me off guard. There were a few moments that genuinely made me tear up. It’s a story about loyalty, family, and a huge, all consuming kind of love. The kind that feels safe and powerful at the same time.
Elisa’s books always give me hope. Hope that maybe, just maybe, men with values, loyalty, and hearts like this really do exist.
Diesel’s Vow is a perfect short read. Emotional, romantic, and deeply satisfying. If you’re looking for a quick but meaningful story that will leave you smiling and maybe a little misty eyed, this one is absolutely worth it.

4.5
as always, love the mix of character and plot, it balanced out really well for me. I loved Diesel's character growth and trusting that he can be there for Sienna and Colt. So readable, perfect to curl up with! Also love that we got character art included - such a nice touch! My favourite part was the last chapter and epilogue, Eliza's HEAs just hit so well and relieve the tension from the danger plotlines. I don't mention this as much as I would like to, but his series is inspired by and set in the Badlands, and aims to spread awareness of the very real crises faced every day by the Pine Ridge community.

Omg! I absolutely loved this book! I could not put it down!
Storyline is perfect and the characters 😍
Diesel. What can I say about this man! He is perfect! Loving, loyal, protective. He try's to deny his feelings for Sienna but his feelings win.
Sienna had a rough life, her family disowned her, she was on her own with Colt. Then she met Diesel. She fell in love with him. She got into an altercation and diesel was there to protect her.
They are the perfect couple and I need more of them!
This is a MUST read !
I would like to thank Eliza for the amazing opportunity to beta read this book! I cant wait to read your upcoming books🖤🖤🖤

Book 3 of the Tempest Knights MC series. Can be read as a standalone.
'She’s the family he never thought he deserved. He’s the home she never thought she’d find. But when her past comes for her, can he protect her without losing everything?'
The plot was intriguing and exciting and well paced. World building continues to excel and impress. The characters drove the storyline and they were very compelling and complex and perfectly steamy together. All in all a great addition to the series. Thoroughly enjoyed and highly recommend.
Grab a copy, kick back and enjoy!.

Sienna is a single mom and Diesel is a MC biker. Diesel knows he wants Sienna and he is ready to make her his.
A lovely story between two strong and lovable characters. Sienna is a vibrant woman and mom to the cutest little boy. It is no wonder Diesel falls for them both. He is a great hero. He is honorable and loyal.
The story moves at a quick pace and there is lots of spicy action. It is only 160 pages and will keep you riveted until the last page.

I fell in love with this story. Diesel deserved so much more than he was allowing himself. And I loved his Sienna found a family in the MC. These two were both amazing people. And they deserved one another. Deserved to live one another. I loved the intensity between these two. The story itself was so good. Written so well. The characters were amazing. The chaos and danger kept me reading. And I didn’t mind the spice at all. This is the first book I’ve read from this author and it definitely won’t be the last.
Review of advance copy
A journey that took time for a family of Sienna, Diesel, and Colt to completely establish.
There's a protectiveness right from the start, a found family, and beautiful signs of affection and care.
Women don't avoid danger when someone dear's life is on the line, but it can be reckless, one can get hurt or worse and should be more patient and wait, especially when their men are handling things.
Impressive Colt's grandma's reaction.

I have been looking forward to reading Diesel and Sienna's story wand was not disappointed, the bond between them was so good, as was Diesel's bond with her son. I enjoyed getting to know more about their backgrounds and seeing that no what was happening around them, to them and between them, their connection stayed strong. The danger and suspense played out well and I just loved seeing them together, as they were always meant to be.

The minute Sienna and Diesel lay eyes on one another they know their connection is deep. Diesel however keeps his distance for far to long and when Sienna gets tired of waiting he realizes that he is throwing away the thing he loves most. This book is a slow burn romance and is sweet and steamy. I can’t wait for book for in this series. If you love a MC romance with alpha men who are overprotective, possessive and dangerous to anyone who is outside their circle, this is the series for you.

So far I’ve read every book in this series and have yet to be disappointed. ER has a way of bringing the characters to life no matter the length of her books. I’ve read the longer books and her short stories- 45-50 pages, just as in this book - we get a developed background on characters we’ve seen in the other books and shines a spotlight on them and keeps you engaged.

I loved Diesel and Eliza's story. It is heartwarming and had me cheering the on to finding happiness. The background details were tragic but one that I could identify with going to college and the parties that have tragic endings for some college girls. The book is descriptive with compelling characters that draws you in and keeps you glued to the pages.

This sweet, steamy age-gap MC romance. Has a great story, character's and suspense. And furiously protective men who would burn the would down to protect the women they love. I would absolutely recommend adding it to your TBR list.

This is Book 3 in the series, all are interconnected standalones and each one is amazing.. I have to say that this series has quickly become my guilty pleasure i can't get enough of the Tempest Knights, each one is brilliantly written and each MMC is delightfully scrumptious, each in their own way! Yum!!

I’ve been waiting for this book to come out! Maybe it’s because I have a 5 yr old named Colt as well or because I’m absolutely in love with this series. Diesel and Sierra are amazing! Another great read from Eliza.

Loved it!!
Loved reading Diesel’s Vow. Once I started reading this book I had a hard time putting it down. Sienna and Diesel’s story was intense, action packed and the chemistry between them was extremely HOT. Loved their story!!

This is the book I have been waiting for and Eliza did not disappoint. In book 3 of The Tempest Knight series we get to know what is going on between Diesel and Sienna. The reason why he hold her at arm’s length.
If you love a morally grey man who treats his woman right then read this book and the others in the Templars Knight series. While this book can be read as a standalone, the overall experience is improved if the books are read in order.

This was an absolutely delicious story. I was hooked from the very beginning I could not put it down and I tell you what chef kiss. The author did an amazing job and I'm so grateful I got to read it..

What a wonderful story of love and loyalty! Diesel and Sienna had it long time brewing and it was really refreshing to see them work it out and build a future together. I just want to live in the story now feasting on more and more 🫶

This wasn’t my favorite. I can’t appreciate insta-love when the H has trouble committing.
