WELCOME TO THE DIAMOND BACK RANCH: where the cowboys are hot, the drama is real, and city girls like Lottie Wright are in way over their heads.

Lottie has spent her whole life chasing success—or at least what it’s supposed to look like. The perfect corporate job. The perfect banker boyfriend. The perfect life in London. But when she’s suddenly fired and catches her boyfriend cheating, she does what any totally rational person would do… and gets on a plane to her family’s ranch in Wyoming.
Cole Miller is rugged ex-rodeo star and absolutely not interested in a city girl playing cowgirl on the Diamond Back ranch - even if they did end up in a steamy tangle on her arrival in Jackson Hole. But as Lottie trades designer suits for cowboy boots, she starts to realise she might be a little more country than she thought. And when a rival ranch threatens everything, she’s not about to let them win, especially when it means proving to Cole - and herself - that she’s got what it takes to earn her place.

For fans of Elsie Silver, Devney Perry and B.K. Borison, Untamed Heart is a slow-burn, high-heat cowboy romance with banter, tension, and a love as wild as the Rockies.
