Typhoon Fury (Oregon Files 12)

Hired to search for a collection of paintings worth half a billion dollars, Juan Cabrillo and the crew of the Oregon soon find themselves in much deeper waters. The vicious leader of a Filipino insurgency is not only using them to finance his attacks, he has stumbled upon one of the most lethal secrets of World War II: a Japanese-developed drug, designed, but never used, to turn soldiers into super-warriors. To stop him, the Oregon must not only take on the rebel commander, but a South African mercenary intent on getting his own hands on the drug, a massive swarm of torpedo drones targeting the U.S. Navy, an approaching megastorm, and, just possibly, a war that could envelop the entire Asian continent.
