Her Sanctuary. Texas Vampires, #1

A woman surviving on the edge of a dark frontier strikes a sensual bargain with a stranger hiding a dangerous secret.In a post-apocalyptic future, creatures who've hidden in the shadows for millennia are freed to roam in a world shrouded in darkness. Rancher Kate McKinnon runs Sanctuary Ranch-a last refuge on the western frontier. While running herd over her cowhands and integrating refugees into their self-sufficient refuge, she escapes her responsibilities the only way she has left-via radio to pockets of other survivors.
One man, Ty Bennett, is her confidante, and she thinks she might be falling in love with his deep, rasping voice. Although they've never met, he seems to know her heart. On a patrol to scavenge supplies, Kate and her cowboys are surrounded by a gang of renegades intent on claiming her. Rescue comes unexpectedly by a militaristic band led by the man she's spent so many hours talking to through the dark nights.
She brings him home only to discover she's brought vampires inside the refuge. Already half in love with the human woman, Ty offers added muscle to her defenses and promises to move her people to safety. Fighting his own nature and appetites, he seeks redemption for his many sins but can't control his hunger to possess Kate. Getting past her prejudice and choking responsibilities tests his seductive powers.
