The other wants everything Jude built to burn. He has no choice but to become the Ghost again, one quiet move at a time, without his wife ever finding out what she really married.

He was overlooked, underestimated… and mopping your floor. Frank Ashford was supposed to conquer the tech world. But brilliance alone doesn’t pay bills—or buy power.

And somewhere between power and survival, Ella—the daughter of the man who gave him a chance—may be the only one who can save him… or break him. The deeper he digs, the darker the truth becomes.

When Frank solves the impossible, he doesn’t just unlock data—he unlocks power. But with every step forward, he uncovers betrayal, lies, and a deadly conspiracy that could cost him everything—including the only person who ever believed in him.
