In the stormy wastes of Canada's Baffin Island, treasure hunters Sam and Remi Fargo make an astonishing discovery - a Viking longship frozen in the Arctic ice . . . But what is more astonishing still is the longship's cargo - a hoard of pre-Colombian artefacts from Mexico. This tantalizing mystery sends the couple to Central America in search of further evidence - and into a heap of trouble. For Sam and Remi's find puts them on the trail of legendary jewel the Eye of Heaven, which also sees other less scrupulous - and murderous - treasure hunters racing to get there first. It's a chase that takes them into jungles, ancient temples and secret tombs on a life-or-death hunt for the solution to a thousand-year-old mystery . . .
