Book excerpt: It is the year 480 BC and the greatest army ever gathered in the ancient world is on the march to conquer all of Greece. An irresistible force, they destroy whatever dares to stand in their path. One man steps forward to stop them, followed by 300 companions. His chances are next to nil, yet he goes without hesitation. This man is a king. His name is Leonidas. And his companions are Spartans. They go to stop the Persian advance and meet their destiny at the narrows known as the Hot Gates. This is the account of the battle of Thermopylae. A small contingent of 300 Spartan warriors will hold off the thrust of the Persian invasion for three days of intense battle. We witness these events through the eyes of the twelve-year old Spartan boy, Agis, who has followed his father into battle and is eventually invited by Leonidas to take his rightful place in the battle at the Hot Gates.
