Mountain Time

Six weeks. That’s all the time I have before the summer rodeo run begins, and I need to stay focused.

My goal is simple—become a world champion bull rider.

And I only have one rule—No girlfriends. No exceptions.

But when I agree to spend the spring shoeing horses in the Colorado mountains, the last thing I expect to find is Kacey Hart. She’s everything I wasn’t looking for but suddenly can’t resist—smart, independent, and heartbreakingly beautiful. She’s spent years guarding her heart, convinced men only want her for her family’s ranch. But I want her for so much more.

As I shamelessly flirt and slowly gain Kacey’s trust, desire sparks and lines get blurred. The closer the summer run gets, the more I need her, in my bed, in my heart, in my life.

And when my summer run gets turned upside down, I do the one thing I swore I never would—I ask her to come with me. Now, it’s not just a world title on the line, it’s my heart. The road to gold is brutal, but losing Kacey? That might just break me.

About The Covers

Where western romance meets true works of art

When it came time to dream up our book covers, we knew we wanted two things:
1. To showcase the beauty and authenticity of the western lifestyle.
2. To make each one a true work of art.

That vision led us to Amanda Wentz, a talented California artist who shares our love for the western industry and way of life. Together, we worked to bring the characters of Diamond Hart Ranch to life—capturing not just their personalities, but the spirit, energy, and truth of the rodeo world.

Each cover in the Diamond Hart Ranch series begins as an original painting by Amanda before being transformed into the final, stunning book cover you see on our shelves. This collaboration allows us to celebrate art in all its forms, and as authors, we believe deeply in supporting fellow artists who pour their passion into their craft.

Our hope is that every time you pick up one of our books, you’re holding not just a story—but a piece of art created with care, authenticity, and heart.
