On the orders of his boyhood friend, now King Philip of Macedon, Aristotle postpones his dreams of succeeding Plato as leader of the Academy in Athens and reluctantly arrives in the Macedonian capital of Pella to tutor the king’s adolescent sons. An early illness has left one son with the intellect of a child; the other is destined for greatness but struggles between a keen mind that craves instruction and the pressures of a society that demands his prowess as a soldier. Initially Aristotle hopes for a short stay in what he considers the brutal backwater of his childhood. But, as a man of relentless curiosity and reason, Aristotle warms to the challenge of instructing his young charges, particularly Alexander, in whom he recognizes a kindred spirit, an engaged, questioning mind coupled with a unique sense of position and destiny.
