Fire from heaven - Mary Renault

Alexander's beauty, strength, and defiance were
apparent from birth, but his boyhood honed those gifts into the makings of a king.
His mother, Olympias, and his father, King Philip of Macedon, fought each other for
their son's loyalty, teaching Alexander politics and vengeance from the cradle. His
love for the youth Hephaistion taught him trust, while Aristotle's tutoring provoked
his mind and Homer's Iliad fueled his aspirations. Killing his first man in battle
at the age of twelve, he became regent at sixteen and commander of Macedon's cavalry
at eighteen, so that by the time his father was murdered, Alexander's skills had
grown to match his fiery ambition.
