Iceberg

High seas explorer Dirk Pitt must stop an American millionaire from using impoverished nations for his own personal experiments in this #1 New York Times-bestselling action adventure series.

A routine survey mission over the North Atlantic exposes a missing luxury yacht frozen inside a million-ton mass of ice. The ship had vanished en route to a secret White House rendezvous, making it the responsibility of the National Underwater and Marine Agency to find out what happened. In other words, it's time for Dirk Pitt to cut his sunny, California vacation short and get back to work.

Of course, when Pitt arrives on the scene and discovers the charred remains of the entire crew, who burned alive but never left their posts, he begins to suspect the tragic loss of the ship to be only the first, deliberate step in a far more sinister plan.

In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.

The main differences lie in artwork style, availability, price, and collector appeal. Ultimately, the choice between standard and variant covers depends on personal preference, budget, and individual collecting goals.
