Clive Cussler Ghost Soldier is a New York Times and USA Today bestselling action-adventure thriller written by Mike Maden, continuing Clive Cussler's legendary Oregon Files series.

The story follows Juan Cabrillo and the elite mercenary crew aboard their state-of-the-art warship, the Oregon. The action opens during World War II, when an American airman is captured and imprisoned in a Japanese research center developing chemical and biological weapons. In the present day, a dangerous arms dealer known only as "the Vendor" has been selling $80 billion worth of weaponry abandoned after the United States' withdrawal from Afghanistan — a threat that puts Cabrillo and his crew on a high-stakes mission to stop a global catastrophe before it's too late.
