Jonathan Preston Imminent Threat

World War II has finally ended, but not for Jonathan Preston—the US Army’s most successful covert operative—a new mission is just beginning. The US Navy and Preston and his team of intelligence agents race against time to stop two rogue Japanese submarines from attacking the east coast of the US with biological weapons capable of inflicting unimaginable casualties.While the US Navy frantically attempts to find and destroy the submarines, Jonathan Preston and his team of counterintelligence agents rush to track down Japanese agents positioned to take possession of the biological agent when the subs arrive off the US east coast. Preston’s WWII nemesis, Japanese intelligence agent Asami Nakada, however, has other plans as she evades US operatives and moves to attack Washington DC, and Philadelphia from the land, while the sub’s bombers attack New York City.
