Arctic drift
(Large Print Book)

NUMA director Dirk Pitt and his children, Dirk Jr. and Summer, have reason to believe there's a connection between a discovery to reverse global warming, a series of unexplained deaths in British Columbia and a rash of international incidents between the U.S. and one of its closest allies. They also know they have very little time to find it before events escalate out of control. Their only real clue might be mysterious mineral traced to a long-ago expedition from which there were no survivors. If Pitt and his colleague Al Giordino aren't careful, the same fate may await them.
