Two Spartan boys grow up together, and become inseparable friends. One is a prince of Sparta, destined to rule this ancient Greek state, the other a slave, or helot, who serves the young prince. In the harsh training camps, or agoges, where boys are groomed to become the great warriors of Spartan fame, their skills are honed and brutally tested. Only citizens may aspire to the warrior's Red Cloak, and one of the tests is the annual crypteia, or hunting of the helots. A beautiful and mysterious young Sibyl speaks of an uprising of the slaves. The Oracles warn of a deadly conflict between two ruling factions. Evil forces will challenge the two boys and test their loyalties, as secret truths about their own identities are revealed.
