Clive Cussler Ghost Soldier is the eighteenth installment in The Oregon Files series, written by Mike Maden. Published by G.P. Putnam's Sons, this paperback edition runs 432 pages.

Juan Cabrillo and the crew of the Oregon investigate a deadly mystery when African jihadis attack a Nigerian regiment using American weapons. The trail leads from Afghanistan to Kuala Lumpur as they track a mysterious arms dealer known only as the Vendor, whose scheme involves unleashing biotoxins. A parallel storyline set in 1945 follows an American airman captured by the Japanese and sent to a research center for chemical and biological weapons experiments.

A New York Times and USA Today Bestseller, Ghost Soldier received a starred review from Kirkus, calling it "an exciting adventure that's worthy of the Cussler name." Publishers Weekly praised the novel as "entertaining" with "vivid, bloody, and occasionally jaw-dropping" action that "fires on all cylinders."
