3 Alpha Cowboys, One Omega City Girl, 3 Months of Forced Proximity - ALL The Spice
Format: Kindle
What could be better than a Cowboy Romance? How about THREE cowboys. If that Reverse Harem reveal doesn't peak your interest, what if I told you that all the cowboys are also Alphas & our FMC is an Omega?
Interested yet? Thought so....
Finding out that there is an entire sub-genre (sub-sub-genre??) of non-shifter Alphas & Omega books has been a recent discovery that I am quite enjoying. Up until this last month I had only seen the Alpha / Omega trope in association with Paranormal Shifter Romance.
However, this new-to-me concept introduces all the fun of Alpha & Omega pheromones, heat cycles, & knotting with no were-creature trope required.
None of that unnecessary slobber or shedding found here! OK there was some shedding, but that was just from the three adorable adopted cats featured in this story. Oh, and maybe some drool on my end as I through some of the spicier scenes.
The spice in this one is hotter'n a blister bug in a pepper patch -- or some other Cash approved country saying.
Speaking of Cash...I'm pretty sure I need to send Harley a Thank You card for writing these spectacular men. Maybe a gift basket? How does one appropriately show gratitude to an author for creating truly exceptional male character.
Which is, in fact, what all the Alphas in this book are. They hit all the book boyfriend tropes:
🩷 Cash Winslow: Your typical golden retriever cowboy. He is tall, blonde, and has a joke or "cowboy-ish" for almost any situation.
💕Scent: Fresh sage, strong coffee, old leather.
🩷 Walker Stone: Tall, dark, & broody this Cowboy is the enforcer of the group. He is also a HUGE flirt & say all the right things!
💕Scent: Cedar & Cinnamon
🩷 Ridge Colter: The stoic & reserved ginger has a heart of gold behind the walls he tries to put up.
💕Scent: Honey & Fresh Bread
The FMC, Sophia Hollis, has her hands....and other places....full with these three.
Fresh out of a very toxic (trigger warning) relationship with her ex-Alpha, she has no idea what it means to be truly cherished as an Omega.
When she inherited the Wild Hearts Ranch, she figured she would travel from her home in Chicago to Montana, sell the ranch, and be on her way with enough cash to pay off her debts and start a new life for herself.
What she didn't expect was for that inheritance to come with terms. Terms that dictate she live on the ranch for three months before she can sell.
Three months.....with three hot Alphas....what could go wrong?
"Three months in Montana with three Alphas, a bull named Brutus who has it out for me, and I have no idea if this small town even has a heat clinic. What could possibly go wrong?" - pg. 27
Nothing....absolutely nothing goes wrong...in fact, after reading this book I would say that things went very VERY right for her.
Without giving too much away, here are just some of my top highlights & notes from the book:
Instant alpha / omega scent recognition.
Shirtless Cowboys.....a lot of shirtless cowboys.
A guest house with a library & swinging chair. (Sadly no on-page library spice)
Ranch / Animal Sanctuary.
Alpha sponsored shopping trip. (Yes - Dressing Room Fun Occurred)
Junk Measuring (With actual measuring tape)
Late Night Stargazing
Lord Weasleton of a Grandson (Seriously....somebody take this guy out back)
Bull Riding & Rodeo (because....of course)
Omega Heat
Guard Dog Bull (Seriously his name is Bruno & he is very cranky)
Adventures with Ice Cream (Mango might just be my new favorite flavor)
Smutty Bookclub (That I wish I could join....seriously...the themed meetings...the costumes...LMFAO)
Small Town Found Family.....and gossip
Cowboy-isms Version of Truth or Dare
He makes her "O" 7 times just to compete with the MMC in her bookclub book.
And so much more....
For those of you wondering, the true spice starts around 50% in, but the flirting & banter builds the tension in the best of ways.
If you are looking for your next Alpha / Omega Cowboys Romance I suggest you take this one for a ride.

Sweet But With Depth!
Format: Kindle
“maybe, just maybe, some things are worth chasing across the sky. Even if you never catch them.”
This is a sweet, cozy OV romance—but it actually has unexpected depth. I picked this up expecting a light read with low angst. And, while I got a low angst read—it was so much more than that. It’s people piecing themselves back together after serious hurts, and learning it’s okay to be vulnerable. Learning it’s okay to allow yourself to be loved
The characters are well rounded and very real, including the “broody” cowboy that could have easily been a stereotype—but was actually one of the best in the whole book.
It’s got just the right level of spice, and boy is it well written! I couldn’t put it down. This is no shallow OV read, this has heart and soul. It’s absolutely beautifully written. It honestly deserves more than five stars!

read it for the cowboys
Format: Kindle
it was a fun, engaging read. there was a lot of time spent on emphasizing how hot these cowboys were ...so that was pretty enjoyable. i love a soft (but hard when you need to be) man -- and these guys were all pillow-soft but also, touch her and die vibes. plus, heats & alpha/omega & knotting - i am in, like flynn!
i didn't quite enjoy the influencer/blogger bits but that's a personal preference - but otherwise, it was a cute story that i would recommend.

Cozy Cowboy Omegaverse 🤠
Format: Kindle
This book is so good and super refreshing for a cozy omegaverse ❤️ I love the grumpy sunshine banter, chosen family, emotional healing, and acceptance. I love the blog parts of this book too, I was just giggling and kicking my feet the whole time!
The characters are rich and interesting and the story is short and sweet and very well written.
100% recommend, 11/10!!

Swoony Cowboys meet a Headstrong City Girl…
Format: Kindle
4.25/5⭐️
Wild Hearts Ranch has my heart!! When Harley Knight teased this book in one of her other books, I was interested to see how it would turn out. I expected there to be more tension and conflict between the FMC and MMCs (at least at the beginning) considering Sophia just dropped into Montana to inherit a ranch she’d never been to, and not only that, but a ranch that was verbally promised to Cash, Walker, and Ridge by the late owner. Thankfully all of the tension was mostly emotional pining which I can deal with since it was light, full of fluff, but the story touched on heavier topics in such a wonderful light. grief comes in many forms, and all of the MCs were able to find happiness -despite their grief- in their connections with each other. If you’re looking for a small town, cowboy, scent matched, omegaverse story that will put you on a medium cycle of emotions as you read it, please look no further! Long live Wild Hearts Ranch!!
