Baffin Island, North-Western Canada: Husband-and-wife team Sami and Remi Fargo are on an environmental expedition to the Arctic, when to their astonishment they discover a Viking ship in the ice, perfectly preserved-and filled with pre-Columbian artefacts from Mexico. It’s a combination history suggests shouldn’t be possible. As the couple plunge into their research, tantalizing 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-begin to emerge. But so do many dangerous people … Soon the Fargos find themselves on the run through jungles, temples, and secret tombs, caught between treasure hunters, crime cartels, and those with a far more personal motivation for stopping them. At the end of the road will be the solution to a thousand-year-old mystery-or death.
