Baffin Island: Sam and Remi Fargo are on a climate-control expedition in the Arctic, when they discover a Viking ship in the ice, perfectly preserved-and filled with pre-Columbian artefacts from Mexico.
How can that be? As they research, clues about a link between the Vikings and the legendary Toltec, feathered serpent-god Quetzalcoatl and a fabled object known as the Eye of Heaven - soon emerge. And the Fargos find themselves on the run from treasure hunters, crime cartels, and those with far more personal motivations for stopping them from unearthing the solution to a thousand-year-old mystery . . .
