North Korea, a Communist nation in desperate financial straits, concentrates its military resources on a scientist bent on swiftly creating missile technology that can take out other countries’ satellites in space; disseminate nuclear payloads to all parts of the earth, thus giving it the power to extort trillions from the rest of the world; and be sold to terrorists and rogue nations at exceedingly high prices.
To protect its investment, North Korea takes no chances. A super-skilled North Korean assassin with the latest lethal methods is dispatched to secretly kill the scientist’s worldwide competitors.
Meantime, the U.S. military plucks Marine reservist Will Parker from retirement. His mission? Penetrate dangerous North Korea, and flesh out its leading military scientist from an entourage of three doppelgangers–Parker roomed with the real guy his freshman year in college.
At the same time, with the help of a North Korean asset, the FBI finally connects the dots, and starts on the trail of the North Korean assassin, hoping to catch him before he kills again.
A Northern Thunder is about a longtime military man relearning to do the right thing for the right reasons, with the whole world at stake.
