The key to creation - Kevin J. Anderson

After long voyages, encountering hurricanes and sea monsters, Criston Vora from Tierra and Saan of Uraba race to the legendary promised land of Terravitae. Saan's quest is to find the Key to Creation, a weapon that may defeat Uraba's enemies, and Criston wants vengeance against the monstrous Leviathan that ruined his life long ago.

Back home, two opposing continents and religions clash for the remnants of a sacred city, unleashing their hatred in a war that could end both civilisations. Queen Anjine and Soldan-Shah Omra are driven by mutual loathing, heaping atrocity upon atrocity in an escalating conflict that only their gods can end.

And amidst the carnage, the secretive Saedrans follow their own agenda, manipulating both sides with the ultimate goal of completing the Map of All Things, which will bring about the return of the world's Creator.
