Perfect for you if...

You love dark romance where the heroine is damaged and dangerous, not just broken and rescued.
You're drawn to motorcycle club romance with genuine emotional stakes beyond the club politics.
You want a revenge story where the female lead stays in control of her own reckoning, even as she lets someone in.

Maybe not for you if...

You prefer your romance lighter and your heroines unburdened by trauma that shapes their every move.
You're uncomfortable with cults, manipulation, or exploration of institutional abuse as backstory.
You need a clear separation between the dark plot and the romance—this book weaves them together tightly.

About this book

A woman raised in a cult where education, opinions, and pleasure were forbidden escapes on the eve of her forced marriage to the cult leader, Jonathan Walker, after her mother sacrifices her life. Driven by her mother's dying wish, she spends a decade planning revenge against Jonathan and the brother she left behind. When she returns to execute her plan, she realizes she needs help and turns to Hunter King, the vice president of a powerful Texan motorcycle club with military experience. Hunter is determined to pull her toward safety, but she knows her path toward destroying the cult leader requires her to become ruthless herself—a transformation that may cost her everything. Stone Cold Hearted is a standalone dark contemporary romance set in the Ruthless Creatures universe. It features dual point of view, a reverse grumpy/sunshine dynamic, and concludes with a happy ending.
