He fired her once. Now she's standing in his penthouse—caring for the only person he can't afford to lose.

Manhattan mogul Julian Black keeps his life airtight: schedules, silence, control. Then Ivy Hart—ex-employee, expert rule-breaker, and the last woman he should want—walks in as his daughter's new nanny. Clara adores her. Julian doesn't do adoration...or second chances. But Ivy brings laughter to the marble halls, challenge to every order, and a dangerous warmth he can't ignore.

Their history crackles: six weeks in his company, one spectacular firing, a chemistry neither of them managed to forget. Now they're forced into close quarters—bedtime stories across glass walls, midnight debates that feel too much like confessions, a near-kiss that shatters his defenses. Ivy's future is calling; Julian's empire is expanding; and the line between boss and something far messier keeps blurring.

When ambition collides with the fragile family they're building, both must decide what they're willing to risk: the armor that kept them safe, or the love that makes them brave. Sharp banter, found-family feels, and a slow-burn billionaire/single-dad romance with a guaranteed swoon—because some fires are worth lighting twice.
