His Battered Submissive by Brandi Evans

Getting her back was easy. Keeping her safe was murder.

Dallas Detective and Dom Maddox Westbrook is in love with the wrong woman: the wife of a sadistic, abusive jerk. Maddox has worked more domestic abuse cases than he cares to count, but he takes one look at frightened Katlyn Harris and falls hard. But like a professional, he puts his feelings aside and relocates her to safety—or so he thinks.
Katlyn has lived in abject terror since her husband abducted her from what was supposed to be a secret location. Every day, she wonders if this will be the day Jeff finally kills her. She’s nearly given up hope of rescue, but when Jeff learns the cops are closing in, he hurries to move her. In the rush, she manages to escape and runs straight into the detective who has never stopped looking for her.

Love can be tricky when a cop falls for an abuse victim, trickier still when that cop is a Dom. Maddox can’t be Kat’s Dom. The abuse she’s suffered at her ex’s hand would not allow that sort of relationship, and Maddox doubts he could ever not be a Dom. Like being a cop, being a Dom is who he is, but Kat surprises him with her strength, her resilience, and her submissiveness. In her, he finds a depth of courage and passion he never expected. But will love be enough to save them against a past determined to destroy them?
