Description

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 the Rocky Mountains.

Cole Miller is rugged ex-rodeo star and absolutely not interested in a city girl playing cowgirl on the 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 realize 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.

Lottie Wright pensaba tener su vida bajo control en Londres: un buen trabajo en marketing, una relación estable y una rutina que, aunque vacía, le daba seguridad. Pero cuando todo se desmorona su empleo, su relación y su confianza acepta la invitación de su prima Lil para pasar el verano en Wyoming, en un rancho que necesita ayuda desesperadamente para sobrevivir. Lo que Lottie no esperaba era que entre caballos, montañas y amaneceres infinitos, encontraría a Cole, un hombre que representa todo lo opuesto a su vida anterior: sincero, protector y con una historia marcada por la pérdida.
Mientras las diferencias entre sus mundos parecen irreconciliables, la conexión entre ellos crece con cada día compartido. Sin embargo, el regreso de su ex y los secretos que rodean al rancho pondrán a prueba no solo su amor, sino también la versión de sí misma que Lottie creía conocer. Entre la lealtad, el perdón y la libertad, deberá decidir si seguir el camino seguro o apostar todo por un corazón salvaje.

This was so easy to get into and delivered all the best cowboy romance tropes. The banter was so fun, the found family trope was everything and I’m so happy for our main characters - they deserve this kinda love 💜.

Thank you to Pan Macmillan for my ARC!

I really enjoyed this one! I loved that the author switched up the “typical” Western romance by featuring a British protagonist with roots to the ranch. The writing was so fun and engaging that I couldn’t put it down. Lottie was a great main character and Cole was a swoon worthy MMC: I loved the world building of the ranch and I can’t wait for the next book!

This was a nice quick easy cowboy read. Lottie is a down on her luck city girl in London who just lost her job and found her boyfriend cheating on her. Not knowing what else to do she impulsively decides to fly to America where she spent her best summers on a ranch living wild and free. We see Lottie try to find herself, find love, and put away her past.
Overall I enjoyed the setup of the story and the characters. Lottie is just doing her best trying to find where she fits, even when it's such an easy answer. Love Cole and his straightforward cowboy-ness. Their love story is so sweet. The other characters on the ranch are awesome as well. The drama at the end was tantalizing. I would've liked to see the follow-up with Lottie's parents. It was a sweet ending though.

The first few pages hooked me right away, so 🤞. Also, love a short read. And yup - it was as good as Elsie Silver! I really liked both Lottie and Cole, and the side characters added just enough without stealing the spotlight.

Lottie leaves her cheating ex in London and heads to Wyoming, where her mom was from. She meets a hot cowboy and it gets hot. There’s an outdoor scene and plenty of cowboy energy, but no one-horse moment. Lottie can ride her own damn horse!
