Rowen Gale is brilliant, powerful, and emotionally unreachable. A billionaire tech mogul raising his niece in quiet isolation, he runs his life with precision and control. Penny is hired to care for the child. The rules are clear: No crossing lines. No emotional entanglements. But living under the same roof changes everything. Rowen watches the way Penny brings warmth into his home, how his niece opens up around her, how the silence he’s built begins to soften. Penny sees past his reserve to the man who carries too much responsibility alone—and the desire he works hard to suppress. Professional boundaries blur in the late hours. Tension builds in the glances they don’t acknowledge. The chemistry between them is undeniable and growing hotter and harder to resist. And once the truth is impossible to ignore, they have to decide whether following the rules matters more than taking a chance on love.
