THE DIAMOND BACK RANCH IS BACK in this spicy second installment in the hottest new cowboy romance series. . .

Hestia Hampton never meant to stay in Wyoming. The ink-stained, sharp-tongued tattoo artist came to the Diamond Back for a breather - one month to lick her wounds after a toxic ex-situationship in London and to mourn the studio she left behind. She’s here for open skies, fresh inspiration, and maybe a wild night or two. Not for him.
Jesse Bennington is temptation on two legs. A retired bull rider with a smile that could melt steel and shoulders built for sin, he’s sworn to take care of his family, no matter the cost. Even if it means climbing back into the ring. Even if it means breaking his own heart.
So when he and Hestia agree on a no-strings fling, it should be simple. But nothing’s simple when desire runs this deep, and under the wide Wyoming skies, rules are meant to be broken . . .

READERS ARE FALLING FOR THE DIAMOND BACK RANCH . . .

'A must read for all cowboy romance lovers out there!'
'If you’re fans of Elsie Silver and Lyla Sage this may be your new cowboy obsession!'
'I absolutely LOVED this book, I devoured it.'

Arc review out 26th March

⭐️⭐️⭐️⭐️⭐️
🌶️🌶️🌶️

She swore it was only temporary…but he makes forever look tempting.

I was so thrilled when I got approved for this arc. I finished Untamed Heart and immediately after I finished I headed on over to apply for this. I really enjoyed Gemma’s Untamed Heart, but book number two is something else entirely 😮‍💨 and I am here for it.

We met Hestia and Jesse in book one, the feisty black cat tattoo artist FMC and the world’s most adorable golden retriever reformed playboy MMC. We knew from the get go that these two were going to be 🔥 and their attraction is instant - chapter 1 spice ladies!

After that these two start with a mutually beneficial relationship but both of them quickly realise they are falling and this is turning into something neither of them were expecting. There is extra drama in this book that I was just missing in book 1, that and having my full name thrown around as a nickname in this book did funny things to me…

This book is full of heart, self acceptance, swoon worthy cowboys and an ultimate HEA. Don’t get me started on Jesse’s relationship with his Mum 😭

Thank you so much to Gemma, NetGalley and Pan MacMillan for the opportunity to read this arc, I loved it.

This book completely exceeded my expectations! It’s my first book by this author so I was jumping in mid series and must admit the first couple of chapters I did feel that and like I was maybe missing some background/ build up but once I got a little further in it was clear this can definitely be read as a stand alone. I do think I’ll go back and read book 1 though as I loved Cole and Lottie so think I’d enjoy their story!

Hestia is visiting Lottie at Diamond Back Ranch from London, staying for just a few weeks, and has instant chemistry with bull rider Jesse. At first it’s just physical, but quickly they both realise there are feelings involved that are getting stronger and stronger.

Some parts of their story are messy, Hestia has a pretty toxic past and there were times I wanted to scream at them both! But I really felt their emotions and enjoyed the author’s writing a lot. I didn’t want to put it down and couldn’t wait for them to finally get their HEA! I really hope we see lots of them in future books…and that Lil might be next?!

Huge thanks to the author, publisher and NetGalley for this ARC.

Hestia and Jesse are everything! So this is my first ever cowboy romance and after this perfect book I am so going to start down into this rabbit hole. I will do so by reading the first book of this series.
I loved everything about the characters. Hestia is broken and Jesse mends her piece by piece without her even realizing it until the very end. I adore their connection, which starts off very steamy, but quickly turns into something deep and life-changing.
I also often had to shed some tears because the people surrounding Hestia treat her with so much love and appreciation anybody can only wish for.
I also enjoy Jesse a lot.
He does not force her to say or do anything and always supports her. He never imposes the feeling on her that she is too much on the contrary he cant get enough of her.
The ending of the book was amazing and touching.
I am really happy that this was my first Cowboy romance.

I loved the first book between Lottie and Cole, but Hestia and Jesse - holy guacamole - they may have taken first place as my favourite opposites attract couple.

I found the mental health rep was well done, until midway, the toxicity of Cal ruined the vibe - I hated that Hestia felt compelled to leave Jesse as she was reminded that she “wasn’t good enough for him” because of her history with Cal and the relationships she grew up observing.

The reunion between Hestia and Jesse was equally gorgeous and frustrating. Chrissy getting in the way of Hestia confessing her love to Jesse face to face could have prevented his accident but then it wouldn’t have made an entertaining end 😂

I really enjoyed the story, although parts were frustrating - for the right reasons (let my girl get her man!!) - it was a wild enjoyable ride!

Thank you Netgalley for the eARC in exchange for an honest review.
Reckless Vow is the second in Gemma Morr's interconnected cowboy romance series, 'A Diamond Black Ranch'. It follows a Black Cat tattoo artist from London and a Golden Retriever cowboy from Wyoming.
I will start by saying I have not read Untamed Heart, the first in the series, and I think my reading enjoyment really suffered because of this. I love interconnected romances and often will read them in order but have sometimes picked up a random one and found that I've still enjoyed the story. Unfortunately I found that I was missing quite a lot here by not reading the first book as i felt like it started in the middle of their romance. I love spice and appreciate when it starts early but I felt like I'd missed some chapters leading up to it for them so it lacked the tension and build up that I love to read. I didn't really understand why they very quickly loved each other when I didn't feel like there was much build up, besides a few hook ups in the early chapters. It felt quite insta love to me although I appreciate that I may have missed some of their build up in Untamed Heart.

Having read a few cowboy romances, I did have a few issues with the way Hestia reacted to Jesse's job and his quickness to get back to it at the beginning of the book. I also felt everything with Luci could have been explored a bit more - that was an interesting part that could have added a bit more to Hestia as a character instead of making all her POVs be just about Jesse. Romance is my favourite genre to read but I like my main characters to have their own jobs/lives so that not every conversation/interaction is about their main love interest, personally.

Other than that, it was a spicy cowboy that was fun to read. I'm sure that fans of book 1 will enjoy the continuation of the series! And I am definitely intrigued by Lil's story which was teased at the end!

Thank you @netgalley and @panmacmillan for this ARC, I'm beyond grateful because it was one of the 2026 releases I was most looking forward to.

I had a great time with Untamed Heart but since the book is very short, I felt like I didn't really know the characters at the end. This volume is longer and well-developed. I read it in less than 24 hours. Gemma, what did you put in this book to make it so addictive?!

I was so eager to read Jesse's story because he stole my heart in the first book. And I wasn't disappointed at all: he was exactly as I had imagined him. He's a truly good man, hardworking and soooo charming. He wears kindness on his face. I was giggling and tapping my feet every time he flirted with Hestia. His relationship with his family was so sweet and he does so much for the people he loves.

I instantly loved Hestia, who is a badass and fun-loving woman who, unfortunately, hasn't always been treated the way she deserves. Falling in love wasn't part of the plan when she had her life and tattoo business in London but she didn't expect to meet such an attractive cowboy... I loved seeing her open up about her insecurities throughout the book confiding in Jesse, Lottie, Cole, Bailey and even through her mare, Luci. I truly loved all those moments which only increased my love for this found family.

Can we talk about the INCREDIBLE chemistry between Jesse and Hestia?😋 It was definitely fire between them. It's spicy, passionate but it's so much more than just physical attraction. Between them, it's natural, almost inevitable. They don't need to pretend to be someone else to be loved completely.

Thank you to NetGalley and Panmacmillan for this ARC 💜

If I had a good time with the first book “Untamed Heart”, of the Diamond Back Ranch series, I hoped to love this second book even more. Finally, they’re both for me at the same place in my heart.

I want to start by thanking Gemma for introducing Jessy’s point of view in this book. It adds so much more depth, emotion and interest to the story and characters.

Since the beginning of this series, I have really loved Jessy’s character. He has such a tender heart; he is shiny, funny, and a good man. I truly love his personality and his relationship with his family.
But I love even more his patience, kindness, and support toward Hestia.

I needed more time to appreciate Hestia, but in the end, I really love her! She is such a complex character, with so many insecurities and issues. She hasn’t been well loved by her family, but she becomes a truly good person and woman.

If I really like Jessy and Hestia as individuals, I didn’t feel butterflies in my stomach or a spark between them as a couple. Their relationship starts as a spicy one, and unfortunately, those spicy moments never really stop and take up too much space. I wanted more emotional moments and connection without physical intimacy. In the end, not much happens, and it felt a bit long, even though Gemma’s writing is always a pleasure to read.
I would also have appreciated more development between Hestia and her family, as we never really get any explanations.

I still had a good time with all these characters : Jessy, Hestia, Lottie, Cole and Bailey, but I will love more details and actions.

After absolutely loving book one, I was really excited to dive into Reckless Vow. Overall, I did thoroughly enjoy it — the chemistry was strong, the tension was there, and Gemma definitely knows how to pull you into the drama.

That said, I struggled a little more to fully connect with this one. I can’t put my finger on why? I loved Jesse and Hestia in book 1 and usually eat up opposites attract. Hestia is withdrawn and guarded when it came to love, some parts of the relationship progression felt a bit rushed for this to be part of her character to me. I wanted a little more time to really sit in that emotional shift, because it had the potential to hit even harder. At times, it felt like we moved past some important moments quite quickly.

Even so, I was still invested in the story and the characters, and there were definitely scenes that reminded me why I loved this world in the first place. The found family is really good in this series! It just didn’t quite reach the same level for me as book one.

Overall, a solid and enjoyable read — just not quite a five-star for me.

However I am super interested and on the edge of my seat for Lils story who I assume is up next in the series that auction at the end and the introduction to a past love had me hooked for what to come her way! And I’m really looking forward to potentially getting in that lady’s head!

I knew within the first 2 chapters of Reckless Vow I was going to love this book. The spice starts almost immediately and despite not knowing much about the main characters yet, due to Gemma's clever writing i was already fully invested in them both!
Hestia is a bad ass and im so proud of how far she grows as a person in this book.
Fleeing her toxic ex in London, Hestia arrives in Diamond Back Ranch to spend some time with her bestie Lottie and regroup. Meeting bull rider Jesse the sexual chemistry sizzles immediately and neither of them can ignore it. With her time at the ranch Limited, our girl makes an important booking... (not saying anything else so there are no spoilers 🤪) is this the start of the shift between the pair?
There are challenges along the way including both of them fighting their own demons, i thought this was well written even though there was slight miscommunication going on.
I thoroughly enjoyed this read and cant wait to see what comes next from Gemma 👌

After visiting her best friend Lottie in the US, Hestia is certain of one thing—she’ll never fall for a cowboy. Her life, her tattoo business, and her future are firmly rooted in London. Falling in love was never part of the plan… until Jesse. Their connection is instant, the chemistry undeniable, and suddenly Hestia is questioning everything she thought she wanted. Could she really give up her entire life for a cowboy?

Oh my god, this book. I thought Untamed Heart was incredible, but this somehow surpassed it. I genuinely didn’t think Gemma could top that story—and yet she absolutely did. I am coming off of an emotional rollercoaster and needed to take a moment. I love Jesse with my whole heart, and Hestia is a total badass queen who deserves to be worshipped. I also loved getting updates on Lottie and Cole, Lil was amazing. I’d love to know her back story.

Gemma Gemma Gemma what are you doing to me, girl ??

I’ve laughed , I’ve cried , I’ve panicked , I’ve swooned . I’m gonna need extra face cream tonight in the hope I don’t have more creases !! What an emotional book !! I loved every second and read it in a day !!!

What an absolute joy to return to Diamond Back for Jesse and Hestia’s story. I loved Untamed Heart but I think I loved Reckless Vow even more. Gemma Morr has written an emotional, heartfelt tale that had me hooked from the beginning - with a fast burn romance and top notch spice that was absolutely delicious!

Hestia is such a fun FMC - she’s sassy and sharp, with deeply-rooted vulnerability that makes her so real, even though there were moments where I wanted to shake her!!

Jesse is ideal book boyfriend material - patient, sexy, kind, and sizzling hot. I loved him so much - and his fearless love for Hestia even when she was spooked was catnip to a romantic like me. What a total babe.

Reckless Vow was an easy, accessible read with a great pace, laugh-out-loud moments, and a lot of lovely side characters. Exactly what I look for an a contemporary romance. I sincerely hope we’ll be back at Diamond Back for another cowboy romance before long!

🤠Reckless Vow is out on 26 March 2026 and is available for pre-order 📚

This is an honest ARC review, with thanks to the author and publisher ♥️📚

⭐⭐⭐⭐️⭐️♾️

Reckless Vow, book two in the Diamond Ranch series by thankyou Pan Mcmillan , Gemma & Netgalley for this ARC. I settled in with a wine to enjoy this cowboy ride 💜 sorry Gemma for my reactions in real time 😂

When this fell into my approved I was screaming, I loved Untamed Heart & boy this second installment had me HOOKED. I read it in one sitting. Gemma has a way of making the read easy and addictive.

Hestia, our alternative FMC, a girl with emotional baggage who starts falling for Jesse, our HOT vibe golden retreiver cowboy MMC was EVERYTHING. 

I loved the alternative nods being an alt girl, the bands, the look, everything felt so relatable. Goth cowgirl is a energy I can get on board with. Jesse, is SWOOOOOON worthy. Their love story is a battle of internal demons of being unworthy to intense devoation. The SPICE 🥵 CHRIST.

I'm hoping from the ending there is a book three into diamond ranch series as this found family and their stories untold, I need more 💜

Plus the playlist is FIRE💜

Well I thought Gem couldn't get any better than Untamed Heart but I was wrong. I think I love Hes and Jesse just as much as Lottie and Cole!

This book made me kick my feet, laugh, cry, blush at the spice from THE GET GO! Hot. That's all I'll say.

I really felt seen by Hes and the way her emotional trauma manifested in who she was. Towards the end I was crying as her revelation of the difference between who she was and who she thought her trauma made her be. I loved that she turned the other way, instead of resorting to our base reaction of violence or snapping. She walked away, head held high and I felt so proud of her, crying as I felt that so deeply within myself.

As someone with childhood trauma, I related to Hes' story so much, and felt so seen.

Thank you Pan Mac and Netgalley for the ARC.

All opinions are my own of course, even though I love Gem dearly! I cannot wait to see what she does next!

a huge thank you to PanMacmillan for this e-arc!! i had so much fun going back to the diamond back ranch! we got to see so much more of the places and characters i fell in love reading book 1.

I loved that jesse and hestia got their own book! they were my absolute favourite thing in book 1, and from there i knew i would love this. especially being in my cowboy era now, i loved being in the ranch, and also reading more about the rodeo side of things.

this book was significantly hotter than the last one and i didn't mind one bit! everything was so jesse and hestia coded and i really loved them together. but i would have loved to read a bit more build-up at the start. however, this book was already longer than the first one, so i feel like we are going in right direction!!

and the most amazing thing: LIL AND RYDER SINCLAIR CLEARLY BEING THE THING IN THE NEXT BOOK?? EX FIANCÉ?? im so ready for that!! im already ready to go back to the ranch!!

Thank you to NetGalley and pan macmillan for the opportunity to read this ARC. This is the second book in the diamond back Ranch series by Gemma Morr. I always tend to enjoy the second book in a series more than the first even though I absolutely loved untamed heart. The second book tends to have an FMC who is Feistier, has more banter and has a little bit more about her. Hestia has been in a toxic relationship for the last five years and in order to have a break, she travels to Wyoming to spend some time with her best friend Lottie. Hestia has a Goth Barbie aesthetic. She is a tattoo artist and has a body covered in meaningful tattoos. She doesn’t feel she is worthy of love, but Jesse the bull rider, turned ranch hand, is here to prove her wrong.

Thank you NetGalley for the chance to read this arc.
I am so excited to read Hestia’s book. I loved her in the first book and I can’t wait to get to know her better.
The way Hestia views herself completely broke my heart. She deserves the entire world and she just doesn’t believe it.
Jesse is such a sweetheart. A big softy, I love seeing him with his mother and sisters.
This book had me crying, giggling, gasping, and really hoping for both MCs to get their s**t together!
I really loved getting to see how Lottie and Cole’s relationship progressed too.
I need a book explaining everything with Lil and Ryder asap!
I’m enjoying falling in love with Diamond Back Ranch and everyone that lives there. This is quickly becoming one of my favourite series.

Thank you NetGalley and PanMacmillan for this ARC.

It did take me a while to get back into this book and I think that is because it throws you straight into Jessie and Hesita's hookup relationship but once I got into it and I did end up liking this book.

It also took me a while to warm up to Hestia but I did end up really liking her because she is such a complex character and I loved getting to lean everything about her. I loved seeing her relationship with Jessie's family as those scenes were just so cute and fun.

I liked Jessie because he was such a kind guy and done everything for his family, also I really enjoyed the relationship he has with his family.

The way this book sets up for the next book makes me so exited for that!

Tempted to buy my boyfriend a cowboy hat and some wranglers after reading this, not gonna lie.
This was such a wild ride (no pun intended) because we literally get thrown into Jesse’s and Hestia’s relationship. It starts quite firey and keeps going like that but my god THEY ARE HOT.
Especially because Hestia is a fellow Sleep Token girlie and general an alt girlie and hello? Alt girlie x cowboy?? I felt so seen.

I also adore how it highlighted mental struggles with accepting what you deserve for yourself being affected by your past. I felt a bit called out but in a good way if that makes sense?

But yes. I recommend this asap. Please read.

Reckless Vow is book 2 in the Diamond Ranch series I’m focuses on Hestia and Jesse. Hestia is a firecracker of a woman who is visiting her best friend Lottie in the US. Her roots are all in London and she has no intention of fallen in love whilst on holiday. Enter Jesse, they have an instant connection. This book takes you through their journey. I enjoyed reading this book and it’s always nice in book 2 when you get to catch up with characters from the first book.

A second book of swoony, Wyoming-set temptation. Hestia and Jesse had electric chemistry, and the tattoo-artist-meets-retired-bull-rider vibes worked.

I struggled with the miscommunication trope, hence the star drop, but the angst and heat delivered. Thank you to PanMacmillan for the ARC opportunity 💛🤠

I liked this book but going into it I expected it to hit more than it did. I really like the MMC up until the end but of the book. Towards the end of the book it seemed really toxic and I just couldn’t actually imagine them together anymore. The first 90% was good and I like how they supported each other and helped each other with family issue and trauma.

Reckless Vow by Gemma Moir is the second book in the Diamond Back Ranch series. After loving the first book, I was really excited to dive into this one and grateful to receive an ARC but unfortunately, it didn’t quite hit the same for me.

I genuinely liked the main characters and thought the premise had a lot of potential. That said, the miscommunication trope pulled me out of the story, which made it harder for me to fully connect and enjoy the romance.

Even though this one wasn’t a standout for me, I’m still invested in the series and will absolutely be keeping an eye out for Lil’s book 👀

Hestia follows her best friend, Lottie from inner city London to a ranch in Wyoming, similarly finding romance and purpose. Swapping the slow burn of the first novel with a more "purposeful" beginning for the central couple, "Reckless Vow" will really work for fans of the series. Hestia popped off the page in "Untamed Heart" so I was glad that this centred on her. The ending perfectly lines up a third book so it will be good news to many that there's more to come.
Thanks to NetGalley and the publishers for the advanced copy in exchange for an honest review.
