ICE ODYSSEY
The world lay frozen under a thousand feet of ice. Only in the Eight
Cities of the Matto Grosso did men still live, hunting the wary ice
whales for meat and oil, and following the creed of the Ice Mother which foretold the end of all life in ultimate cold.
But legend told of a
city far to the north - fabled New York - whose towers rose above the
ice, whose crypts held the forgotten lore that might bring warmth to
Earth once again. In the best ice ship in the Eight Cities, Konrad
Arflane embarked on the impossible voyable to New York - an odyssey of
incredible peril and adventure with a shattering discovery at the
journey's end...
