The Rancher by Kate Pearce

On the legendary ranch she can now call home, one woman searches for her place in her birth family—and finds so much more . . . Now that she’s completed her engineering degree, Rachel Ford Morgan is trying to find her footing around her birth father and her four brothers. She gets a chance to prove herself when she discovers worrisome fault lines around an abandoned silver mine. But they’re nothing compared to the cowboy who seems determined to shake up her world . . .

Cauy Lymond doesn’t take kindly to the woman nosing around his property—especially since she’s a Morgan. He came home just to keep his father’s failing ranch out of their super-wealthy hands. But he soon realizes that Rachel’s skill—and admirable courage—may be the only things that can shore up the old mine that threatens both their futures. Still, it will take pouring all of their blood, sweat, and secrets into saving the land—and ultimately, themselves—to bring their true feelings for each other to the surface . . .
