On a desolate beach in far northern Scotland, the winter storms have been washing up all manner of things since time began. But buried in the centre of one smaller iceberg is a shard of ancient Viking pottery telling a partial tale of a hidden mysterious island beyond the ice and mist, that was home to a great treasure and even greater horrors. Thawing in the same block of ice was a rotting flap of skin that refused to be identified but had similar skin patterns to a creature not seen for 100 million years. Now, Troy Strom and the enigmatic Elle Burgan race to find the mysterious island of legend, while staying ahead of a group of brutal killers who claim to be the rightful owners of the greatest prize of all - Odin's heart.
