Dr. Talula Erickson, a respected archeologist with Cherokee and Choctaw heritage, and her husband Leif, a Norwegian archeologist, embark on an expedition to Machu Picchu, Peru to uncover the ancient water systems of the Inca civilization. What they discover instead is a path to a legendary artifact — the Eye of the Serpent — an Emerald Stone of immense historical and mystical significance.

Their journey leads them through lush jungles, mysterious temples, and treacherous landscapes, where they encounter shape-shifting jaguar priests and dark forces seeking the stone for their own. With the help of CIA pilot John Miles and Talula’s clairvoyant sister Christine, the Ericksons must navigate ancient rituals and supernatural threats to protect the Eye of the Serpent and unlock its secrets.
