The Protocol Billionaire

Nadia Chen is used to life-or-death stakes, but they usually involve hospital monitors and the crushing weight of her student debt . When she identifies a lethal "kill command" hidden in a medical device update, she reacts instantly to save twelve lives—breaking the law and the equipment to do it.

Enter Elias Vale. He is the "Biotech Billionaire," a reclusive prodigy who views the world as a series of equations to be solved. He doesn’t just hire Nadia to find the saboteur; he "acquires" her, moving her into his high-tech penthouse under Level 40 security.

To uncover the ghost in the machine without alerting the press or the board, they need the ultimate cover story: a marriage of convenience. Now, trapped in a glass fortress with a man who is as devastating as he is cold, Nadia must help him hunt an enemy from within . But as the digital threats turn into real-world danger, Nadia realizes the biggest variable she can’t control is her heart.
