It is the fourteenth century, and one of the most apocalyptic events in human history is set to occur—the coming of the Black Death. History teaches us that a third of Europe's population was destroyed. But what if? What if the plague killed 99 percent of the population instead? How would the world have changed?

This is a look at the history that could have been—a history that stretches across centuries, sees dynasties and nations rise and crumble, and spans horrible famine and magnificent innovation. These are the years of rice and salt.

Through the eyes of soldiers and kings, explorers and philosophers, slaves and scholars, Robinson navigates a world where Buddhism and Islam are the most influential and practiced religions, while Christianity is merely a historical footnote. Probing the most profound questions, Robinson shines his extraordinary light on the place of religion, culture, power—and even love—in this bold New World.
