Translated from the book's back:
Eternal winter reigns on all continents. Humanity retreated into the oceans. A new society has formed in the deep waters of the seas. A world full of danger, intrigue, adventure and hope.
Only a few inches of steel seperate from life and death ...
Humanity was defeated by an unbeatable foe: the climate.
The inhabitants of the "Council of country", a coalition of seven nations, live in domed cities and travel in large number of subs, always in danger of becoming victims of pirates, raiders or other dangers from the deep. Clones are part of the population, as well as are psions.
