The man lay face down and quiet on the snow for what seemed an eternity. If anybody was watching they might have thought he was already dead. The section of snow where he lay, disturbed by his presence, moved off down the slope, carried him over the edge and into the water. A gurgling splash shattered the perfect silence and sent out a wave across the mirror calm water. The wave moved on, growing smaller and smaller until it became a ripple, then a thought... and then it finally disappeared as if it had never been... just like the man. When Jeremy Gibbs and his wife Sophie set off on an extended European holiday, they had no way of knowing that a death on the ice in Greenland, seven hundred years before, had ignited events that would ultimately overtake them... and ravage the world.
