Claiming The Arrogant CEO's Unexpected Heir

One reckless night was never supposed to change anything.

It was meant to remain a beautiful mistake—one neither of them would ever have to explain. Then life moved on, silence settled between them, and Josie built a future around the one secret she never intended to share.

Until everything unravels in the middle of a public hearing.

Nathaniel Callahan has spent his entire life believing every problem can be solved with enough preparation, enough control, and the right legal strategy. Nothing prepares him for the moment he discovers he has a fourteen-month-old son he never knew existed.

Now the powerful billionaire who always has the answers is completely out of his depth.

Determined to claim a place in his son's life, Nathaniel reaches for the only language he's ever trusted—contracts, schedules, and carefully planned solutions. But Josie refuses to let motherhood become another negotiation. If Nathaniel wants to know his son, he'll have to stop acting like a CEO long enough to learn how to become a father... and prove he can earn back the trust of the woman who has every reason to keep him at a distance.

As old feelings refuse to stay buried, impossible choices blur the lines between duty and love, and a tiny little boy quietly changes two stubborn hearts forever, Nathaniel and Josie must decide whether the family they never planned might become the one thing neither of them can bear to lose.
