Iceberg
Clive Cussler
Mass Market Paperback
(Berkley, March 2, 2004)
Frozen inside a million-ton mass of ice-the charred remains of a long missing luxury yacht, vanished en route to a secret White House rendezvous. The only clue to the ship's priceless-and missing-cargo: nine ornately carved rings and the horribly burned bodies of its crew.
