Cyclops (novel)

A wealthy American financier disappears on a treasure hunt in an antique blimp. From Cuban waters, the blimp drifts toward Florida with a crew of dead men—Soviet cosmonauts. Dirk Pitt discovers a shocking scheme: a covert group of U.S. industrialists has put a colony on the moon, a secret base they will defend at any cost. Threatened in space, the Russians are about to strike a savage blow in Cuba—and only Dirk Pitt can stop them. From a Cuban torture chamber to the cold ocean depths, Pitt is racing to defuse an international conspiracy that threatens to shatter the Earth.
