In 330 BC, after defeating Darius III and capturing Persepolis, Alexander seemed to have reached the zenith of his reign. But his ambition was greater than any known map. He decided to continue eastward, pursuing a mythical horizon: the edge of the world. This journey led him to confront not only powerful enemies and the most extreme elements—monsoons, deserts, and icy mountain ranges—but also the unforeseen consequences of his own glory.

In this book, historian Rachel Kousser reconstructs the most unexpected and little-known turn in Alexander's life: the transformation of a brilliant conqueror into a king who had to learn to govern a vast, diverse empire fraught with internal tensions. We witness decisive episodes such as the burning of the great city of Persepolis, the integration of conquered peoples into his army, his attempt to unite East and West, and the toll of advancing toward an uncertain destiny.

Alexander at the End of the World is a story of power and the thirst for conquest, but also of adaptation, failure, and learning. A human and epic portrait of a leader who, in seeking the limits of the world, ended up finding his own.
