If you crave danger, obsession, and morally complicated passion, this dark romance will grip you—but reader discretion is strongly advised.

He served her divorce papers without hearing a single explanation—and exiled her not only from his home, but from the country itself. Years later, Rosa returned with a secret. Their son was dying. Diagnosed with high-risk acute lymphoblastic leukemia, the boy needed a stem-cell transplant from a biological sibling to survive. And to make that possible, Rosa had to conceive again—with the one man who despised her. Her ex-husband. Luciano Mancini. But Rosa refused to reveal the real reason for her return. Getting pregnant by a devil was never going to be easy—especially when that devil hated her. She hadn’t stolen his seed before… but this time, she was ready to commit the sin if it meant saving her child. Seeing his ex-wife again—no longer innocent, no longer obedient—awakened something Luciano had never felt for any woman. He wanted her and… he wanted to own her this time. But Rosa was already slipping beyond his grasp. Because Dr. DeLuca, the man treating her son, was in love with her. He was willing to accept her in any condition—even if she carried her ex-husband’s child once more. When life finally offered Rosa safety, love, and a future free from cruelty… why would she ever return to the Italian Don? Except Luciano Mancini isn’t going to let her go. No one takes what belongs to him.
