Imminent Threat 
A Jonathan Preston Novel

World War Two is over—but not for Jonathan Preston!

The United States Army’s most successful covert operative to come out of WWII, Jonathan Preston, and his team of agents race against time to stop a rogue Japanese submarine from attacking the US with a biological weapon capable of inflicting unimaginable casualties.

Shortly before the war ends, an Imperial Japanese intelligence czar implements a sinister plan of revenge against the US to strike Washington DC and New York City with a deadly biological weapon. If the US Navy cannot find and destroy the submarine, Jonathan Preston and his operatives must stop the transfer of the biologic into the hands of a skilled female Japanese agent already in the United States poised to take possession of the terrifying weapon.

Preston leads the hunt through the streets of Baltimore and Washington DC, the beaches and ocean waters of North Carolina, and the Virginia countryside before tangling with the unpredictable, stealthy, and deadly agent. Action, history, espionage, romance—it’s all there.
