An Imminent Threat

A Delta operator and his team race against time to stop a terror network from detonating dirty bombs in cities across the United States.

When the clock is ticking and innocent lives are at risk, Master Sergeant Rob Walker and his Delta team are the only thing standing between the United States and a terror network determined to detonate dirty bombs in cities across the country.

With a ruthless terrorist mastermind at the helm, one previously thought to be dead, Rob and his team must hurry to identify and stop the source of the bombs before it's too late.

From the Middle East to the UK, Mexico and the United States, Rob and his team battle through a thrilling hunt. But will they find them in time? Or will many more die in the name of global jihad?

If the heart-pounding action of Brad Thor’s "Spymaster" had you on the edge of your seat, you'll love "An Imminent Threat."
