Clive Cussler is the author or coauthor of more than seventy previous books in five best-selling series, including Dirk Pitt, NUMA Files, Oregon Files, Isaac Bell, and Sam and Remi Fargo. His life nearly parallels that of his hero Dirk Pitt. Whether searching for lost aircraft or leading expeditions to find famous shipwrecks, he and his NUMA crew of volunteers have discovered more than seventy-five lost ships of historic significance, including the long-lost Confederate submarine Hunley, which was raised in 2000 with much press publicity. Like Pitt, Cussler collects classic automobiles. His collection features more than eighty examples of custom coachwork. Cussler lives in Arizona.
Graham Brown is the author of Black Rain and Black Sun, and the coauthor with Cussler of Devil's Gate, The Storm, Zero Hour, Ghost Ship, The Pharaoh's Secret, and Nighthawk. A pilot and an attorney, he lives near Nashville.
