What to read after Inca Gold?

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.
