In the depths of the sea, he is drawn to a luminescent stone which will seal his fate... There is also the pretty Agnes, kept alive in a sphere of liquid by a genius without scruples, who Duncan Dimanche is trying to save. They don''t know it yet, but the destinies of these heroes are about to cross... With Agito Cosmos, Olivier Milhaud and Fabien Mense thrust us into a suspenseful saga of unbridled imagination, original characters and sophisticated intrigues.
