"As for me, I swear to you: I did not recount even half of what I heard or saw. Besides, I was neither an explorer nor a writer. I was simply the son of a merchant. I was Marco Polo." Imagine a world that looks like a half-finished puzzle! Many, many years ago, people's neighborhood was small and the world map had big gaps, like black holes. But all that changed when some "crazy" visionaries decided to fill in the missing pieces. Marco Polo, Columbus, Magellan, Cook, and other pioneers dared to shed light on the black holes of the map. Through this new series, we will become fellow travelers of the greatest explorers, heading for the unknown and diving into the most incredible pages of History and Geography.
