Ruthless Sinner - The Zeta Cartel Novels, #6

Determined to get her mother the healthcare she needs, drop dead gorgeous Spirit Westcott works as a stripper, not caring a jot that it cements her reputation as the village bad girl. But when Spirit falls foul of John Cooper, the newest member of the notorious Zeta Cartel, she loses her job. Furious, Spirit confronts Coop-only to discover his secret drug lab. When Coop decides to save her, by disappearing her and keeping her captive, Spirit is less than impressed.
However, she quickly learns that Coop has an even deadlier secret, and one that may drag her into the abyss. When dangerous, single-minded John Cooper learns his best friend was murdered, he resolves to exact bloody vengeance. The knowledge that his prey is a Zeta, one of Mexico's most dangerous cartels, doesn't stop him. Coop joins the organisation, only to discover that finding his prey won't be easy.
To his annoyance, sexy Spirit Westcott is also a spanner in the works. After embarrassing him in public, Coop suddenly finds himself saddled with an unwanted captive, and her cat. Then, just as things couldn't get worse, a killer takes aim at the village girls. As Coop is drawn further into the cartel, he is forced to make decisions that may cost him his life-and that of his love. Ruthless Sinner is a gripping tale of vengeance, murder, cartel violence and finding love in the darkest of times.
It is the sixth novel in the Zeta Cartel series and can be read as a standalone.
