Midnight Thunder by Vicki Lewis Thompson

The lost cowboy…

Thunder Mountain Ranch was the only place cowboy Cade Gallagher had ever called home. But after he and Lexi Simmons broke each other's hearts, he left it behind, along with his foster family. Since then, Cade has drifted, looking for something — anything — to call home. Until a call from Lexi changes everything…

Cade has been gone too long. His foster mother is hospitalised and the ranch is in deep financial trouble. Yet even as his world crumbles, Cade's hunger for Lexi is almost as tangible as the taste of her lips and the way her body fits deliciously against his. It's bittersweet surrender. But Lexi isn't the girl she used to be and she's determined to have the hot cowboy in her bed only if she keeps him out of her heart.
