The Sixth World (Maya Earth Trilogy Book 1)

Two anthropologists, caught in an international intrigue, lead an expedition into the lush hills of California's Central Valley to explore the unimaginable possibility of finding the Mayan civilization that vanished from Central America in the ninth century. They discover ancient, Mayan hieroglyphics that tell of the approaching end of the Mayan Fifth World, a vast treasure of gold and fantastic technology, hidden for centuries in preparation for the new age. As the fateful time draws near, ritual killings occur suggesting the Maya have survived to oversee the new age, and it is up to Amy Parrish and Joe Magee to stop the diabolic plot that threatens to destroy the Maya and the earth itself.
