For National Underwater & Marine Agency crew leader Kurt Austin, an investigation into the sudden deaths of rare whales leads him 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 crew turns up the white-goddess legend -- and a murderous cadre of bio-pirates intent on stealing medicinal secrets worth millions. Soon Austin and his crew realize they're working the opposite ends of the same grand scheme. A billionaire California tycoon is poised to rise to power by monopolizing the earth's vastly depleted freshwater reserves and ultimately dominate the world.
