Invincible

An old flame rekindles in this fan-favorite tale from New York Times bestselling author Joan Johnston...

Wealthy aristocrat Bella Benedict has one last wish: to see her five estranged children happily married. But one of her sons, Max Benedict, has no interest in long-term commitment. Instead, he travels the world, working as a sometime spy for the CIA but mostly cementing his reputation as a rich playboy. When he's asked to investigate a foreign threat against the president, he doesn't think twice about accepting—until he hears who he'll be working with in London.

FBI Special Agent Kristin Lassiter is under investigation and on the verge of losing everything—her savings, her job, her beloved father. So when Bella Benedict approaches her with an offer to pay her mounting debts, she's tempted to accept. But there's a catch, and a big one. Bella wants Kristin to win the heart of her playboy son Max—the very man who broke Kristin's heart years ago and is unaware that he fathered her nine-year-old daughter. If Kristin succeeds, she'll get the money she needs. But can she win Max's heart without falling back in love with him?
