Left on the slopes of the Parnon, Elpis's only flaw is that she was born a girl. She is raised in Athens in the house of a noble, but she wrestles with the boys and hunts in the olive groves like a true daughter of Sparta. When she finds out she is the daughter of the Spartan king of legend, Leonidas himself, her feet lead her back to Sparta, and the father who didn't want her. But war is brewing, and Persia is invading the peaceful shores of Greece. Will her feet lead her safely back to Sparta? Or will she be caught up in the war that threatens to tear her country apart?
