The Aztec Heresy — Paul Christopher

Archaeologist Finn Ryan stumbles upon a mystery dating back to the Spanish Inquisition -- and a secret with catastrophic implications for the present.

In search of a Spanish galleon in the Caribbean, Finn Ryan and her partner, Lord Billy Pilgrim, find evidence of a lost Aztec Codex. The invaluable book, created by fifteenth-century explorer and accused heretic Herman Cortez, is said to reveal the secret location of the lost City of Gold. Finn and Billy soon realize they are not alone in their quest.

Also on the trail is the head of a menacing religious cadre, who would kill to get the Codex first, as well as a sociopathic billionaire, with his own sinister reasons for wanting to possess it. But while trying to find the Codex -- and stay alive -- Finn and Billy come upon an even greater and more explosive secret. This mystery will take them from the jungles of the Yucatan to the Sonoran Desert, where the stakes are life and death -- and the game is just beginning.
