Kate Thompson is a top-secret agent for the Department of Security (DOS), trained to uncover the truth—and bring down the world's most dangerous criminals. Her latest mission: investigate Devon Dragon, a billionaire CEO suspected of masterminding international crimes.

Posing as his personal assistant, Kate expects to find a ruthless villain. But what she discovers is completely unexpected. Devon Dragon is charming, kind, fiercely loyal, and unexpectedly sweet—a man nothing like the cold-hearted criminal she was warned about.

As Kate digs deeper, her mission becomes more complicated—and so do her feelings. Can she trust the man she was sent to take down? And when the lines between duty and desire blur, will Kate risk everything for love... or lose it all to betrayal?
