The Ends of the Earth (original title: Il confine del Mondo) is the third and last part of Valerio Massimo Manfredi's trilogy on Alexander the Great. After the Oracle of Ammon told him he is the son of Zeus, Alexander feels invincible and marches north towards the historic town of Babylon. The beautiful city is ravaged and the Palace of Persepolis, the former residence of King Darius, is burnt to ashes together with the memories of the old Empire. It is now time to start anew and Alexander decides on yet another hard task: unify the Persian people with the Macedonians. As he struggles to convince his countrymen to come to cultural compromises with the Persians, he falls in love with Queen Roxane. And it is this love that gives him the strength to fulfil his epic destiny.
