Shadow Agent: The Network Within (Paperback) (ISBN-13: 9798251917819)

They're not stealing secrets from the outside. They're growing spies from within.

When FBI Unit Chief Sarah Chen uncovers a foreign intelligence operation buried deep inside America's most prestigious universities and Silicon Valley boardrooms, she realizes the threat is bigger than anything she's faced-even the Wellington betrayal that nearly destroyed her.

The target? Quantum computing technology that could shift the global balance of power forever.

As Sarah leads Operation Quantum Guard, she's pulled into a web of coerced scientists, billion-dollar investment fronts, and interagency turf wars that threaten to derail everything. One physicist, forced into espionage against his will, becomes her unlikely ally-but trusting him could be the biggest gamble of her career.

With her relationship with Jake and her daughter Emma hanging in the balance, Sarah must dismantle a network that doesn't officially exist, run a multi-city takedown with zero margin for error, and confront a chilling truth: some enemies are protected by the very diplomacy meant to keep us safe.

Perfect for fans of Brad Thor, Vince Flynn, and Alex Berenson. Start reading today.
