Dirk Pitt is back, in an adventure that is perhaps the most inventive and most exciting of his career – a classic treasure hunt involving an ancient hoard of gold, the secrets of a lost civilization, and an international ring of smugglers, all brought together in a plot that only Clive Cussler could devise.

Inca Gold begins in 1532, when a fleet of ships sails in secret to an island in the middle of an inland sea. There they hide a magnificent treasure more vast than that of any pharaoh. Then they disappear, leaving only a great stone demon to guard their hoard.

In 1578 the legendary Sir Francis Drake captures a Spanish galleon filled with Inca gold and silver and the key to the lost treasure, which included a gigantic chain of gold that belonged to the last Inca king, a masterpiece of ancient technology so huge that it requires two hundred men to lift it. As the galleon is sailed by Drake's crew back to England, an underwater earthquake causes a massive tidal wave that sweeps it into the jungle. Only one man survives to tell the tale….

In 1998 a group of archaeologists is nearly drowned while diving into the depths of a sacrificial pool high in the Andes of Peru. They are saved by the timely arrival of Dirk Pitt, who is in the area on a marine expedition. Pitt soon finds out that his life has been placed in jeopardy as well by smugglers intent on uncovering the lost ancient Incan treasure. Soon, he, his faithful companions, and Dr. Shannon Kelsey, a beautiful young archaeologist, are plunged into a vicious, no-holds-barred struggle to survive.

From then on it becomes a battle of wits in a race against time and danger to find the golden chain, as Pitt finds himself caught up in a struggle with a sinister international family syndicate that deals in stolen works of art, the smuggling of ancient artifacts, and art forgery worth many hundreds of millions of dollars. The clash between the art thieves, the FBI and the Customs Service, a tribe of local Indians, and Pitt, along with his friends from NUMA, two of whom are captured and threatened with execution, rushes toward a wild climax in a subterranean world of darkness and death – for the real key to the mystery, as it turns out, is a previously unknown, unexplored underground river that runs through the ancient treasure chamber.

Inca Gold is Clive Cussler – and Dirk Pitt – at their very best.
