- Baffin Island: Sam and Remi Fargo are on a climate-control expedition in the Arctic, when to their astonishment they discover a Viking ship in the ice, perfectly preserved - and filled with pre-Columbian artifacts from Mexico. How can that be? As they investigate, 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 among treasure-hunters, crime cartels, and those with a far more personal motivation for stopping them. The solution to a thousand-year-old mystery awaits them at the end of the chase - if they manage to survive it.
