The fact that the map of the Ottoman admiral Piri Reis, who lived in the late 15th and first half of the 16th centuries, depicts the coastlines of Antarctica, North and South America, is an amazing mystery for many historians. This novel tells the story of how Muslim travelers discovered America two hundred years before Columbus, which served as the basis for compiling this map. The main character is a young guy who is trying to organize a sea expedition that can protect the inhabitants of Islamic countries from the Mongols and crusaders.
