TWO BESTSELLING AUDIOBOOKS IN ONE PACKAGE Clive Cussler, the author of sixteen consecutive New York Times bestsellers, unleashes a hero for the ages in an electrifying series of unrelenting action and edge-of you seat thrills. THE NUMA FILES COLLECTION SERPENT When Kurt Austin, the leader of a courageous National Underwater & Marine Agency (NUMA) exploration team, rescues beautiful marine archaeologist Nina Kirov off the coast of Morocco, he becomes the next target of Texas industrialist Don Halcon. A madman bent on carving a new nation out of the southwestern United States and Mexico, Halcon's scheme hinges on Nina's recent discovery involving Christopher Columbus, and a priceless pre-Columbian antiquity buried in the battered remains of the sunken Italian luxury liner Andrea Doria. BLUE GOLD An investigation into the sudden deaths of gray whales leads NUMA crew leader Kurt Austin to the Mexican coast, where someone tries to put him and his mini-sub permanently out of commission. Meanwhile, in South America's lush hills, a specially assigned NUMA team discovers a mysterious tribe, a mythical white goddess, and a murderous cadre of bio-pirates intent on stealing medicinal secrets worth millions. Soon, Austin and his crew realize they're working opposite ends of the same grand scheme. But every step toward salvation takes them deeper into a dense jungle of treachery, blackmail, and death.
