The Aztec Heresy

An ancient secret. A lost city. A treasure that could change the world. In search of a Spanish galleon in the Caribbean, archaeologist Finn Ryan and her partner Lord Billy Pilgrim find evidence of a lost Aztec Codex. The invaluable book created by 15th-century explorer and accused heretic Hernan Cortez is said to reveal the secret location of the lost City of Gold. But they are not alone in their quest.
Also on the trail is the head of a menacing religious cadre who'd kill to get it first, and a sociopathic billionaire with his own sinister motives. But while running for their lives, Finn and Billy come upon a more explosive secret that will take them from the Yucatan jungles to the Sonoran Desert, where the stakes are life and death.
