Valentina Soliz knows that normal families don't have tactical security grids, but for the House of Morgan, power is the only language spoken. Years ago, Valentina built a quiet life in an Italian village, a world away from the billionaire secrets of her father's "lost years." But when a coordinated arson attack at a Star Island gala traps her in a corridor of fire, the past doesn't just haunt her, it tries to burn her alive .

William Morgan, a structural engineer who traded the family spotlight for blueprints and hard logic, is the only one who hears the mechanical shift in the HVAC system that saves Valentina's life. As the "Pittsburgh bastard" of the Morgan empire, he knows exactly what it feels like to be an outsider. But when a physical breach of his home proves Valentina wasn't just caught in a fire—she was the target—William is determined to turn his sterile glass mansion into an impenetrable fortress.

As the danger intensifies, Valentina must navigate a world of social manipulation and a tactical mastermind's revenge. In this forced proximity struggle for survival, she must choose: reclaim the independence she fought for or trust the man who calls himself a machine but treats her like his heart
