Husband-and-wife team Sam and Remi Fargo are in Mexico, packing medical supplies in the wake of an earthquake, when they come upon a remarkable discovery--the mummified remains of a man clutching an ancient sealed pot. Within the pot is a Mayan book, a codex larger than any known before.

The book contains astonishing information about the Mayans, their cities, and about mankind itself. The secrets are so powerful that some people would do anything to possess them--as the Fargos are about to find out. Many men and women are going to die for that book.
