Cyber Tracked: The Cobra Project — Eliza March

Rowan O'Malley is wealthy, brilliant, and beautiful, and over time, she's learned to keep her distance from dangerous men.
The self-made business woman, one of the most exceptional cyber hackers alive, dragged herself out of the dark net and developed system security programs that can't be broken.
When an anti-terrorist organization discovers what she created, they'll need her expertise to protect the international military security programs. But once the news about her program gets out, someone her with a billion dollar bounty
Agent Cade James is assigned to get to her before the bounty hunters, keep her alive, and prevent her from completing her newest project…or better yet...buy it. To do that, he'll need to win her trust, and he's been told that doesn't come easily.
He has no idea how capable the fragile beauty is, physically and intellectually. But when his perfect fantasy woman is more willing to seduce him than trust him with her life or her project, he's stunned...and furious.
She's going to need more from Cade than references, especially when he claims his, so called, group represents the good guys. Unfortunately, since there's no trace of them in any government or system, not even in the dark net system, they're either very, very good...or he's a stupid to underestimate her. In spite of all that, he's the one man who's capable of making her forget she's being hunted, and for once, she considers following her heart instead of her head.
She has a plan. No point taking unnecessary chances, because being wrong isn't an option.
