A rogue scientist. A viral weapon. A race to stop then ext global catastrophe.

A U.S. Navy ship crashes into a protected coral reef. An all-electric car veers off-course, killing a powerful Washington insider.

Two freak incidents—one chilling connection.

When Russia invades Ukraine, a top Ukrainian virologist vanishes with a deadly gain-of-function viral formula locked in his memory. He escapes to Europe with his wife and young daughter, ready to sell the formula to the highest bidder.

As nations scramble to secure the weapon, FROG, a secretive intelligence agency, has one mission: assassinate the scientist before the formula goes global.

But when his daughter is kidnapped by a rival force, the mission spins out of control. Now, FROG's elite operatives must navigate a shadow war of mercenaries, spies, and bio-terrorists—where the wrong move could unleash a pandemic the world may not survive.

From thriller author M.H. Sargent comes a gripping, high-octane novel ripped from today’s headlines—perfect for fans of Vince Flynn, Brad Thor, and Mark Greaney.
