Clive Cussler, the #1 New York Times bestselling author, had his adventure and sea thrillers continue to hit bookshelves long after he died in 2020. While this isn't a ghostwriting situation, other writers were hired to continue Cussler's series, with their names appearing on the covers to credit their work. The latest addition is GHOST SOLDIER, the newest installment in the OREGON FILES series, written by Mike Maden. Maden is known for his DRONE series, four of Tom Clancy's Jack Ryan Jr. thrillers, as well as Clive Cussler's Hellburner and Fire Strike.
