After an explosion in the Gulf of Mexico destroys three oil rigs trying to revive a dying field, Kurt Austin and the NUMA Special Projects Team are tapped by the President of the United States to find out what's gone wrong. The trail leads them to a brilliant billionaire in the alternative energy field. Her goal is the end of the oil age; her company has spent billions developing the world's most advanced fuel-cell systems. But is she an environmental hero ... or a rogue genetic engineer?

The NUMA crew discovers that the oil fields are infected with bacteria that are consuming the oil before it can be pumped out of the earth - a bacteria originally lost decades ago when two submarines vanished in the Mediterranean.

With hired killers on his trail, can Kurt Austin locate a submarine that's remained hidden for more than fifty years? And even if he can, can the biological terror that's been unleashed be stopped?
