Tanner Dunn must take the reins of the Rocky Road cattle ranch after his father's stroke. With a brother long gone, a brother deployed, and his youngest brother wanting to leave for his own career, he has his hands full. Still, he's adamant his father receives the best care. But when their adversary's daughter, Amanda Hayden Davis, arrives to provide his father's therapy because she's the best, it becomes more than he's willing to shoulder.

Amanda is not happy she's been assigned to the patriarch of the Dunn family, nor that she is the first Hayden to step foot on Rocky Road Ranch in over twenty years. But she's a ray of sunshine compared to the grumpy eldest son. When she's told to leave before she's started her work, she doesn't budge. No one tells her what to do. She willingly argues with Tanner, often winning. Despite that, she finds herself respecting his work ethic, his moral compass, and his heart. It doesn't help that he also has the shoulders of her dreams and looks amazing in a suit.

Tanner admits he's grateful for Amanda's efforts with his dad, but that doesn't mitigate the damage her family has done to them over the years. It's the Hayden's fault Rocky Road may have to become a Dude ranch, something Tanner has fought against for the last year. The problem is, he's fighting his attraction to Amanda as well. Not only is she kind, but she has a zest for life that he can't resist. But if he gives in to her, will he lose the ranch? Or will resisting her be the biggest mistake of his life?
