The Map of All Things. Terra Incognita, #2

A line in the sand. A wall to the sky. After terrible atrocities by both sides, the religious war between Tierra and Uraba has spread and intensified, irreparably dividing the known world. What started as a series of skirmishes has erupted into a full-blown crusade. Now that the Uraban leader, Soldan-Shah Omra, has captured the ruined city of Ishalem, his construction teams discover a priceless ancient map in an underground vault-a map that can guide brave explorers to the mysterious Key to Creation.
Omra dispatches his adopted son Saan to sail east across the uncharted Middlesea on a quest to find it. In Tierra, Captain Criston Vora sets off in a grand new vessel to explore the great unknown and find the fabled land of Terravitae. But Criston cannot forget how his previous voyage ended in shipwreck and disaster . and the loss of his beloved wife Adrea, who-unknown to him-battles palace intrigues and constant threats in far-off Uraba.
For Adrea is now the wife of the soldan-shah and mother of Omra's adopted son.. The Map of All Things continues Kevin J Anderson's epic fantasy of sailing ships, crusading armies, sea monsters, and enchanted islands.
