On the run from the City soldiers, the Amazons of Tristaine seek refuge deep in the mountains, where an even greater danger awaits. In their new mountain stronghold, a battle rages for the lives and souls of the Amazons of Tristaine. While Jess and her warriors fight a ghostly army, their weakened leader, Shann, must find a way to defeat a powerful demon queen. Shann's only hero is to reveal long-held secrets that will change Brenna and Jess's life forever. The Thesmephoria moon rises over the last bloody confrontation between two great Amazon tribes—the living and the dead—and when the sun dawns, only one queen rules the village.
