Cowboy Loyal by Harper Young

Violet Reed is in debt. Not the student loans/spent-too-much-in-Eurrope-the-year-after-high-school kind of debt. No, because Violet isn’t the kind of girl who got to leave her hometown behind and run off to a new life. She has her mother to take care of, her back to watch. Thanks to her scum father, she owes a drug lord a whole bunch of cash, and it’s pay up or suffer the consequences.
Dane Carter knew from the start that there was something special about auburn-haired, green-eyed Violet. She’s the woman for him, and no other one will do. So when he finds out she’s in trouble, nothing will stop this cowboy from protecting the girl of his dreams.
