He was supposed to be off-limits. She was supposed to be invisible. After her father's death, Alice Bell is forced into a life she never asked for—living under the roof of the powerful Hawthorne family, surrounded by wealth, judgment, and rules she didn't create. The last thing she needs is attention. Especially from him. James Hawthorne is disciplined, untouchable, and used to controlling everything around him. As her stepbrother, he knows the boundaries. He understands the consequences. He should walk away. He doesn't. What starts as tension becomes protection. What feels like safety turns into desire. And the more they try to ignore what's growing between them, the more impossible it becomes to deny. But secrets don't stay hidden forever. When rumors spread and loyalties are tested, Alice and James are forced to confront the truth: loving each other could cost them everything—family, reputation, and the fragile stability they've fought to build. My Step Brother's Dirty Secret is a forbidden, emotionally intense slow-burn romance featuring a strong heroine, a protective yet morally gray hero, and high-stakes drama where love refuses to stay quiet. Perfect for readers who love taboo tension, power dynamics, and deep emotional payoff.
