Blue Gold - Clive Cussler

An investigation into the sudden deaths of rare whales leads Kurt Austin, National Underwater & Marine Agency crew leader, 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 murderous cadre of bio-pirates is intent on stealing medicinal secrets worth millions. Soon Austin realises they’re working the opposite ends of the same grand scheme. A Californian agribusiness tycoon is poised to rise to power by monopolizing the earth’s vastly depleted freshwater reserves and ultimately dominate the world.
