The prosperous city of Ekbatana, situated on overland trade routes, was the capital of a great empire whose army repeatedly repelled attacks from neighbors and protected its people and wealth. The young prince Arslan was being groomed from a young age for the role of a new ruler, but conquering the hearts of those around him—having grown up in the shadow of a ruthless father and an absent mother—proved far easier for him than mastering military art. When Arslan turned fourteen, he took part in his first campaign, which ended in catastrophe: his father was betrayed and the army led by Arslan fell into an enemy trap. Saved by a fearless warrior and a loyal friend, Arslan embarked on a journey that was meant to make him a true king—great, decisive, and just. After all, the prince, who barely met his parents' expectations, possessed what many rulers lacked: a kind heart and an open mind that allowed him to overcome the power of tradition and old prejudices, so he could see a vast and diverse world as it truly is.
